Material Question & general forum question

[Cheezy-Neezy]

Hi everyone,

my first question is about a certain material, which I have a problem with replicating.
Its called Exyd and I tried using a jpg. of water droplets and silver material but that didnt give the correct impression.
Any help or pointers would be greatly appreciated.


Second point is:

how come I cannot post a new topipc in V-ray for Rhino: General or any of the Forums?

Thanks guys!

Could you post a rendering of your material? Your way sounds good.

[Cheezy-Neezy]

LIke this or do you mean it differently?

[Micha]

I would try a much higher bump multiplier and also you could try the vray noise as texture.

[Cheezy-Neezy]

Ok, but how would I make a bump map out of that material?
http://cpetry.github.io/NormalMap-Online/ I use this website. But I have to admit I dont know what to use where when it comes "Normal, Displacement, Ambient Occ. and Splecular". You know what I mean? Like which of these fit in which options in rhino?

[Micha]

I would go to the material bump mapping and select noise as texture. Noise mean it's generated by Vray during rendering, no map conversion is needed. Attached a screenshot from VfR2 (I have no VfR3 running at the moment).

[Cheezy-Neezy]

Ok So I tried It like that. Its beginning to look like something but not quite there yet. I tried playing with the noise settings but that just deformed the surface.

[Micha]

You could play with frequency and maybe octaves (maybe you need to change the noise type to get it working (perlin?)). So you could add a small noise over the large noise. Also bump intensity could be to high.

Depending on the type of Exyd you want to achieve I urge you to experiment by using a Composite texture, slotting two Noise textures (or Noise + Cellular) with different parameters (amplitude/frequency) and then trying different operators to produce a two-layer (shallow and deep) bump effect.
