Re: Photoshop/Shader - Normal Map - Deepening and Combine
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… -
Re: low poly curiosity
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… -
UE4 and Lightmaps... I am so done :(
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… -
Lightmaps
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… -
PBR > Linear Workflow Queries...
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… -
SOLVED: Seam Termination issue
Hello everyone. I was very pleased appearance of new seam termination function, but did not expect that it will cause new problems. Every time I create a new project or re-import color map DDO fails to complete the process on that stage (pic.) I've tried to change a background color or completely remove it and use a random… -
Confused - Lightmaps, LODs, Mipmaps, how works together
Hi, I am really litle bit confused now, how works together Mesh LODs with Texture/Lightmap Mipmaps. I will try explain my problem, but first I tell, what I understand under these terms. 1.0 - Mipmaps in short are textures with different sizes and are "auto generated" by engine if are not defined in texture file (only DDS… -
Re: Sketchbook: Eric Chadwick
Finished the heat refraction effect (I hope) https://github.com/KhronosGroup/glTF-Sample-Assets/pull/127 This one uses counter-rotating Depth and Normal maps, for a moire like distortion effect which aims to obscure the fact that it’s using rotating UVs to distort the refraction to fake something like a heat refraction… -
Re: What Are You Working On? 2014 Edition
Delko's cars inspired me, so I tried to make a 126p in the same style :poly124: -
Re: [Extend Programming] To create you own 3D exporter
for just a model with triangle faces and a UV map (what most formats carry) all you need:* vertex array (3 elements: each holding x,y,z positions) * face array (3 elements: each pointing to the index of the vertex array of that vertex) * uvVertex array (same as vertex, holds U & V coordinates of the UV verts) * uvFace…
