Incorrect. The blue channel has nothing to do with magnitute...Your thinking of how a bump map works. The three channels of a normal map store the ANGLE of normal vectors...Red is X, Green is Y, and Blue is Z. So in any one pixel, there is a value for each channel, giving angle for each axis to direct light which way to…
Instancing within a model will only help with the items perfromance in your 3d package. That said, making duplicates of repetitious items can help when it comes to uv'ing as it can save you time/texture space. Once in game it will be recognized as 1 mesh unless imported in pieces. Tri count for your portfolio is your…
Hey everyone, I've spent the last few good hours researching lightmaps for UE4. I have found some useful info such as: 1) UE4's compression algorithm for lightmaps is using a 2 pixel border for interpolation so you need padding... 2) Your islands should be (as much as possible) be perfectly aligned on the grid. 3) For…
Hi Polycount Community :] Sorry in advance for my awful english, I'm a frog :poly136: I try to have some decent results while generating lightmaps with 3ds max via Vray. First I tried without hlsl shader. The final RT engine (virtools) has some basic blend modes. I used the multiply mode, but then, lightmaps only darken…
Hi guys, so I'm tip-toeing more and more into PBR and reading the resources on the wiki (love the bible <3 ) and I'm trying to get my head around gamma correction and a linear workflow. I understand that when an image is shot via camera, what it actually shoots and what is on display is different due to the gamma…
