Re: HLSL handling cases where texture isn't loaded
You can use a one instruction line : diffuseColor = tex2D(g_TopSampler,IN.UV0.xy);diffuseColor = (diffuseColor != 0) ? diffuseColor : float4(1,1,1,1); the ?: translates to 1 asm instruction -
Re: Crazybump 3ds max shader
In case it helps, here's a quick pseudocode description of CrazyBump's shader (with parallax displacement omitted). All the vectors are in tangent-space. DiffuseColor = DiffuseTexture * (LightVector DOT NormalVector) SpecularColor = SpecularTexture * (HalfVector DOT NormalVector) ^ Gloss OutputColor = (DiffuseColor +… -
Re: Lightmaps: tech pros and cons
Ben Apuna, its simple. If you are baking your lightmaps in a 3d package like max you can setup your lighting so it looks how you want it, then when you actually bake the lightmaps bake them 2 or 4 times darker than they were when you were preview rendering. You could probably do this easily with some exposure control in… -
Re: SOLVED BY USER: Colorswatch for Photoshop doesnt match FBX ?
I'm getting the same issue with swatches.fbx from Quixel Suite 1.8, but with Blender. i.e. in the swatches provided for photoshop (Swatch.aco), the color for Varnished Wood is #c85300, but in the FBX file once imported into Blender, the color is #E59B00 which results in "Undefined" in Ddo. I converted swatch.fbx to ASCII… -
Re: Useful UDK HLSL Trick
I would use a simple approach. Basically all you have to do is : ( 1 - glossiness ) * numofmipmaps. In my case it's 7. My setup : If your are using phong or blinn you might want to multiply your glossiness by 128 in order to get a range of 0 - 1 to avoid value like 180 or 200. But with a cook torrance or a spherical… -

Re: Advice with Learning Shader Programming
LoL this makes me mad. I dont know if it is this hlsl compiler or max but it is crazy. I've put my code into some fancy functions like Xoliul did, to get a better overview. But instead working like before as I would expect it, it does not I've got no compile errors or anything else, but my specular calculation doesn't work… -
Maya HLSL Shader - lcNextGenShader.fx
I'd like to share with you a real-time HLSL Shader for Maya’s Viewport that I wrote as part of my exploration into the wonderful world of HLSL. Try it out, and if you like it, let me know!

Re: Any ideas how this is done?
I'm using DiffuseColor, Spec, AmbientColor, Incandescence, and Shadow. -
Re: 'Good Company' - 3D work
The flag animation is just a simple 'vertex offset' shader with a panned gradient texture and the same texture is used for multiplying/darken the diffusecolor for fake shading. No 'use' of 'normal reconstruction'. I hope you like it! :)
