Hi, firstly I’m quite new into panda3d.
I’m creating grader simulator program, in which the grader is supposed to clean road from snow.
So I have somehow to alter terrain (snow plane) when grader moves over it.
Firstly I tried with GeoMipTerrain and PNMImage. but it went terribly slow to update terrain from image with new tire tracks.
Then I found this video and tried to use shaders.
But even demomaster program gives me this error
:gobj(error): Cg program too complex for driver: /c/Users/.../demomaster-0.8/demo_nature/shaders/vertextexture2_new.sha. Try choosing a different profile.
And basic-shaders-only is turned off.
the same error comes when I add
float4 color = tex2Dlod(tex_0, float4( vtx_texcoord0, 0, 0));
to my vshader.
I’m using ATI HD5850 video card on windows 7.
Anyhow please guide me to right direction, so I could achieve my coal.
