trying to use a .glsl procedural noise but not having much luck

[matthew999]

Hello

im trying to use a .glsl open sorce texture from https://github.com/BrianSharpe/Wombat

but i cant for the life of me get it to work. I appreciate that these textures might be too old for vray support or im missing a trick, any advice would be apreciated.

thanks

We'll investigate. Meanwhile, you can check out the VRayBerconNoise texture, which has some of the referred noise profiles.

Hi Alexsander,

thanks for your reply

yes i have been playing with the vray bercon noise its almost there but what im looking for is a cellular noise that starts from a hexagonal array rather then a grid. Like the attachment below, taken from this site https://briansharpe.wordpress.com/20...simplex-noise/



thanks

Give a shot with the standard Maya cell node, leather node actually

Hi damaggio

I must be blind, but where can I find this Maya node.

Thanks
Matt

Sorry Matthew, I was out on the street when i typed it, its a texture under Maya 3D Texture in the hypershade called Leather, is also decent to fake some foam in the water.

Hello Matthew,

The Wombat code is fine but it's just a collection of functions and not full-fledged shaders. In order to see anything, a main function is needed (the entry point of the shader) which is expected to produce output by writing to gl_FragColor. I'm attaching a couple of very simple shaders, based on Cellular3D and Perlin3D_Deriv, just to illustrate how these can be turned into real shaders.

Best regards,
Ivan
