JIStyles' Skin no likey Max2009
admin
When I try loading JIStyles_skinshader_R3.fx in Max 2009's DirectX Shader material, I get the red wireframe...
I'll email Joel, but has anyone else got it to work in Max 2009?
C:\Program Files\Autodesk\3ds Max 2009\memory(375,14): error X3000: syntax error: unexpected token 'VertexShader'
I'll email Joel, but has anyone else got it to work in Max 2009?

The standardFX does a decent job for what I need it to do.
that is make line 375: (which is also in your error message you posted)
VertexOutput VertexShader_main(ApplicationData IN,uniform half4 LightPosition)
and then later in the technique block at the end do:
VertexShader = compile vs_1_1 VertexShader_main(LightPosition1);
which appears a couple times, replace the second VertexShader with VertexShader_main

Styles) http://www.jistyles.com Description: Another day, another skin shader -- getting believable organics is one of those holy grails of cg, and we're only just starting to get closer to that goal in real-time. After a lot of research into skin, this is my attempt at getting somewhere close to that, so this is my visual approximation. As always, I don't think this shader is quite up to development standards code-wise -- I'm an artist, not a programmer, so don't expect the most pretty code out there ;) happy tinkering! :D -Joel Features: - Diffuse - Soft Light blending algorithm - Normal map lighting model - Translucency kludge (based off melanin and hemoglobin tones) - Correct fresnel ramped specular - 3, 2, and 1 light setup technique's Known nasties: - No shadow occlusion - Controls still quite tweaky - Not fully tested on a wide range of hardware - No depth ramp, it's a constant (eg, no differentiation between a thin ear and a thick skull) Referances & thanks: Ben Cloward - used your normal lighting method too :) Nvidia samples Direct X sdk Shader X2 Polycount Sumea CGtalk */ //=============================Globals============================== half4x4 WorldIT : WorldInverseTranspose < string UIWidget = "None";

by the way TSM the thing you posted used a very old version of the shader as base
Thankyou guys for supporting those still using this.
I've spent the past 2 years under a rock, only to find that this is still being used - on one side I'm humbled that people still use this shader, on the side side... damn! it's old and crusty
Maybe it's time to do some updates... I've been slowly updating my folio over the past months. Maybe it's time to update the shaders too.
rant on...
After this much time I'm rather surprised there isn't a bigger community interest in shaders. Those that do create them aren't that prone to sharing or supporting the art based community, yet there's a large hole to be filled here. I really do hope that this will change in the future... I'm really not one to talk though, since I have abandoned it for this much time myself. We'll see if I can get some updates togethor hey
