• Types of textures
o create all the textures even if you are not using some of them, it is required by model/texture combiner.
o all textures for an item should have the same resolution
o _color - 24 or 32 bit(32 if alpha needed for opacity)
o _normal - 24bit, 3dsmax format (red channel - left; green is up; blue - top). Use flat normal color(128,128,255) if you aren't creating custom normal map
o _mask1 - 32 bit, every channel is used:
1. R - detail map mask
2. G - diffuse and fresnel warp mask
3. B - metalness mask; controls where color and fresnel are suppressed
4. A - selfillum mask; color is drawn from _color. *Always put something in here, even if you are no using selfillum. This is done in order for texture compiler to keep this channel. If its black - it gets thrown out and then shader thinks it's pure white and your item will be full bright
o _mask2 - 32 bit, every channel is used:
1. R - spec intensity
2. G - rimlight intensity
3. B - tint spec by base color, INVERTED! black=tint by base color, white = uses specular color
4. A - scale factor of specular exponent from shader. e.g. if spec. exp set to 16 then this channel values 0...255 will control exponent values from 0...16. Look at hero specular exponent number to get good idea what values to use in this channel for your item.

OP , would be nice of you if you could simplfy above , i'm trying to figure it out too but a bit lost.
thanks!
So this basically means that unless I'm making a direct replacement of her shoulders, hair, wings, or weapon, there can't be any additional cosmetic items for her, and the additional pieces I have done simply can't fit into the game.
Do you think because of things like this, that they plan to change texture sizes/tri counts of heroes or expand the limits?
But can't you unwrap your new modified shoulders for example , into a new empty 256x256 and copy/paste the old parts and add in your stuff. Most probably you will lose detail.
The tri count being 6,710 out of total 7,000 makes it pretty much impossible to fit all the accessories in the LOD0 limit. Interestingly though, her default LOD1 set is 3,029 which doesn't even include the weapon (it has no LOD1 version, and makes the total 3,405 if included), so that's already over the 3,000 limit quoted on the facepunch site. This may be a sign of hope that the limits can be exceeded (unless the true LOD1 limit is 3,500). But either way my combined total for my additional LOD1 items is 490 tris, which is going too far over.
It's all experience anyway, will be able to make fitting items eventually.
About Budgets:
All hero's have 1024x512 texture space.
So taking your queen of pain and adding items to it is going to be an obvious challenge.
However, if the additional items cover up the majority of her body, wouldnt you think that doing so frees up so much texture space? because if it was covered you wouldn't need a 512x512 map for that whole body. Instead you can bring it down to 512x256, or 256x256 leaving you an additional 3x 256x256 texture space.
Remember this, most players would be seeing this character from a locked POV with limited zoom, and most players zoom out. So, Prioritize the things the viewers see the most.
About Polybudgets, It is under the sole discretion of the designer and the team of how much tolerance is given to items with certain polycounts. My general rule of thumb is to make your items as poly efficient as possible, showing the most important parts of the shape that can easily be read from a dota 2 perspective. For lod0 dont show shape where it wont be seen.
Even if it exceeeds the stated poly budget Valve can consider it if it was well made. A well seasoned modeler would understand this once they evaluate your model.
I will summarize this section of requirements in the original post soon.
I've finished a helmet for Enchantress and that helmet plus her base model is 6,920 polys. Just barely scratching the 7,000 poly budget. I guess I got it lucky. But, there should be some sort of "exceptions" later on, or some heroes like Enchantress that are heavy on the poly counts won't ever get full item sets.
