      Forum Rules   07/06/2016

      Introduction   The Squad Team reserves the right to edit, update, add and remove rules at any time. Applicable rules extend to the PM system. Your PMs are private, but the Squad Team may be informed about unacceptable PM content by the receiving party.   Section I: Posting Rules   §1 Show Respect This community can only work if we all respect each other. To that end, it is imperative that any time you engage with another user, either directly or indirectly, you show them respect with the content of your post. In particular refrain from flaming, insulting, abusing, taunting, racism, and other similar types of actions towards other forum users.   §2 Attitude & Behavior Poor attitude and behavior are the most common ways a negative / unsafe environment is created and perpetuated. As such that kind of behavior will not be allowed on these forums. Please be mindful of this rule when posting personal positions and opinions regarding topics which could be considered contentious in nature. As a rule of thumb, keep your posts civil in nature, and refrain from making posts that are likely to incite arguments and create a negative environment. As a privately hosted web forum we reserve the right to maintain an environment that we are happy the majority of our players are comfortable with.   §3 Swearing While we will not strictly moderate every little swear that occurs, please try to avoid excessive bad language. The moderation reserves the right to remove rants and unsuitable content at any time.   §4 Illegal Topics
      Prohibited topics include, but are not limited to: Piracy, drugs (including cannabis), pornography, religion, racism, sexism, homo/trans -phobic content, videos and images showing violent death or serious injury, ‘spam threads’, hacking & griefing (endorsement thereof), religion, politics,  etc. Prohibition may be suspended for some threads if they are found to be suitable by the Moderation (such as scientific debate).
      If there is doubt, the Moderation Team can decide whether a topic is considered illegal.   §5 Attitude towards Squad and the Development Team
      As per §1 and §2, keep in mind to be respectful and reasonable, not only towards all users of the forum, but also towards the Squad Team and towards any ideas and content and the game itself. Criticism is welcome, but if it is not constructive and/or if it is offensive, the Moderation may need to step in. Please refrain from posting if you are upset, angry or drunk, or you may be punished for things you wouldn’t have otherwise written, which is not in anyone's interest.   §6 Language & Legibility
      Please post only in English. Non-English content (including non-legible content) may be removed. If you see someone posting in another language because s/he apparently does not speak English, please report their post - if you can, you may reply in their language to explain their question, but please do translate their and your message so it can be reviewed by the Moderation. ‘Hiding’ insults in non-English posts will be punished harshly. Posts written largely in ‘leetspeak’ or full of spelling / grammatical errors may be treated like non-English content. This rule does not extend to PMs.   §7 Forum structure & Search
      Please ensure when posting a new thread, that the thread is located inside the correct forum section. Check all forum section titles to judge where your thread should belong. Threads created in the wrong forum section will be moved or deleted.
      Before posting a new thread, please make use of the forum search to find older threads about the same topic. In doubt, it is recommended to rather post in an existing thread, unless that thread is years out of date. However, do not bump old threads without adding a new question / answer / insight that wasn’t in that thread before - use common sense.   §8 Thread Titles
      Please name your thread appropriately; the subject title should sum up / explain the content in the thread. If you fail to name your thread properly (such as ‘Hey!’ or ‘Check this out!’ or ‘Help!’), we will either rename or lock the topic. Repeated offense may lead to infractions. The practice of using CAPITALS only in your thread title is not allowed and will be edited or the thread will simply be deleted. Strange or abnormal Unicode characters should be excluded from thread titles for the sake of being distracting and unnecessary.
      §9 Thread Capitalization
      Please ensure that your post is not in all CAPITALS, as this is not allowed. Any threads posted in all caps will subsequently be removed from the forum. Repeated offenses may lead to infractions against your account. This practice is not approved or accepted here. 
        §10 Images in posts
      When posting images, mind the following restrictions:
      .gifs will be allowed and may be removed by Staff if deemed necessary.
      Maximum size for images is 1280x1024.
      Do not include more than ~1 large image per paragraph of text, unless in image collection / announcement threads. Link to further images.
      Consider posting thumbnails. You may post a few more images per post if they are reasonably small, the details are for the Moderation to judge.   §11 The use of BBCode
      It is allowed to use the BBCode in your posts. Over usage is not allowed. You may use the Bold in a reasonable manner but not for the whole text body. You may use the size feature but in a limited reasonable manner. You may not use any of the additional fonts at all. Color may be used to high light a point but again, not for the whole text body. Moderators will be watching for misuse and will edit when required without giving notice. Continued disregard for this rule will result in Moderator action in the form of warnings.   §12 Complaints of Server/Admin Abuse Reports of server/admin abuse will not be posted publicly. All reports concerning this type of behavior should be place in the appropriate sub-forum. http://forums.joinsquad.com/forum/241-report-server-admin-abuse/ All posts made outside of this area will be be removed.   Section II: Reporting & Moderation   §1 Reporting Posts
      There is a Post Report system in place. If you notice a post that violates forum rules, simply use the exclamation mark icon below the users avatar image to send a report to the Moderation. We will then review this post. Your report will not be made public and cannot be linked to your person by anyone outside of the Squad Team. You will not be punished for using the Report system even if the report was false, unless you repeatedly abuse the system to spam it.
      Do not ‘report’ posts by replying directly in public to them. In case of spambots, this prompts them to respond in turn, spamming the forum further. This also fuels flame wars and arguments.   §2 Reporting Moderators
      Moderators are subject to the same forum rules (and some additional rules / exceptions). If you think that a Moderator has treated you unfairly or is otherwise breaking forum rules, please PM the Lead Moderator or any Administrator. Do not accuse Moderators in public, the Squad Team will treat every complaint seriously and it is in our interest to discipline or remove Moderators who are known to break forum rules.   §3 Respect Squad Team members and Moderators
      Do not ignore or argue against Admin, Moderator or Dev instructions on the forum. If you have a complaint, as per §2, please inform the Team in private. You are expected to follow orders given by the Moderation, Administration and Development Team, and it is necessary for smooth running of the forum to respect their decisions. Being stubborn or ignoring warnings will lead to harsher punishments - however, we do not tolerate Moderator / Admin abuse of power / privileges, so do not hesitate to inform other Team members if you feel treated unfairly.   §4 Bans and multiple accounts
      If your account is temporarily or permanently banned, do NOT create another account. Bypassing a ban will result in further action, and a permanent ban of all of your accounts.
      You are not allowed to have more than one account for any reason. If you share an internet connection with another user who has their own account, it might happen that this account is incorrectly identified as a secondary account - please get in touch with the Moderation or Administration to resolve such issues.

  1. Hello. In this tutorial I would like to talk about texel density. If you will work some time in the commercial gaming companies, you will definitely meet this concept in their documentation. And this is no accident, because it is really important aspect of asset production. So what is texel density and why it so important? What is texel density? Before answering this question first of all it is necessary to define what is a texel... From wikipedia: Texel simple language - it is a pixel of the texture. Even if these concepts are similar, but not identical, you can perceive texel the same as the pixel. And a texel density is the number of texels per unit of the squre virtual (game) space. Why texel density is important? It's simple. The higher a texel density, the more detailed the texture on the screen. And the opposite: the less texture density, the more blurred the texture will be on the screen. But that's not all... Game scenes are usually composed of a plurality of objects. And because the games do teams consisting of several people, and because it is difficult to determine the size of your texture relative to other objects this may lead to the fact that each object in the scene will have varying degrees of detail. Here is an example from Internet: As you can see on this picture walls and barrels are more crisp while the texture on the floor is very blurry. That is why it is important that the texel density of the textures should be standardized at least for an environment assets. But above all, it should be said that the texel density is not a mandatory rule. It can vary depending on your needs and possibilities, well at least if you know what you're doing. You can vary texel density inside a single object to distribute texture space proportional to the number of details that you want to show. For example if you doing the vehicle, you can double texel dencity on parts with high dencity of details like steel hawser, or for parts which player will be able to see very close (for example parts of the cabin) and you can decrese texel density for parts which is gonna be hard to reach for the player (such as the bottom) to save some texture space. Here some examples: And here what you gonna get if you if you do not pay enough attention to this issue: Should we use any software for this? I have met a couple of ways on the internet about how to calculate it manually. But I will not bring this methods here, because it's hard to imagine a person who will do it manually every time. Generally every game company (at least with whom I have worked) has its own piece of software (usually a script) that is measuring the texure density of UV shells that you are selecting. But we are not game company and we need some free solutions for that. And we have some of them for different programs (3ds max, Maya etc.) in the Internet and they are free. I will discuss about one solution for 3ds max (becasue it's harder to find). It's called Advanced UV Normaliser. The problem is that from version 2.0 it's not free. I also heard that TexTools can somehow adjust texel density but I've never tried because I don't like TexTools. Anyway. I've got an old version of Advanced UV Normaliser which you can download here. And here is an official site where you can buy lastest version of this script in case you need it. How to run this script? You can drag & drop it in max viewport. Or u can select it via Scripts>Run Script. What's next? First of all you must decide what value you will be using. And the problem is that it depends on your project. But in today's games (at least in those that I work) I have seen the values of 400-512 pixel per meter (p/m) on average. And if we talk about Unreal, in case of 512 p/m we have to use 2048x2048 texture for square 4x4 meters. That sounds reasonable if you ask me. Because in Unreal one floor is usually 3-4 meters height (link). This mean that I suggest you to use for average texel rate any number between 400 and 512 (Not less than 400 and not higher than 512). However it's you should decide, I did not insist. Next you should set up your units (Unreal using centimeters). Here is a tutorial about how to set up centimeters in Max. Pay attention that you can leave "Generic Units" in "Units Setup" tab and only change system units to centimeters (And I suggest you to do that, because max works more handy in this case). So how do we set texel density for crist sake? Fist of all you should add Unwrap UVW modifier to your model and launch Advanced UV Normaliser. Next you select any UV Shell for that you want to measure. After that In Advanced UV Normaliser interface you select Custom (1.) and set a texture dimentions that you would like to use (2.) and then you press Get Texel Density, after that you will see the result in the Ratio Geom/Pixel section (4.) In our case its 4.1819 pixels per centimeter (400 p/m). If you don't like the number that you get, you can rescale your UV Shells or change texture dimentions untill you get something that you like. And this is basically how you set up texel density. Thats all, thanks for your attention. Any questions?
