Glowing Rhino

[dalomar_cg]

I hadn't messed around with translucent materials in a while, so yesterday I opened up the Rhino Logo file and started getting back into it. This is what resulted, which I've used to replace my old background. Its not 100% yet, but I think it came out cool. I guess this is the "dark side" of the Rhino logo ;D

The only real addition is an interior offset in the horn which has an emmissive material applied (the eye has it too)...the rest of the rhino is the translucent material

Re: Glowing Rhino

Dalomar, great looking render...I have a question? ???

I'm trying to have an emissive material give off an atmospheric glow as opposed to glowing on an adjacent material. Is this something better accomplished in Photoshop or can it be done in VRay. Any suggestions? ;D

Re: Glowing Rhino

That's something that's really much more for photoshop for two reasons. First is simple, at this point we don't have what's need to actually do them. Volumetric environments should be on their way, but today there's no real options. Second, its significantly faster to just do it in PS. Even to work with volumetrics takes time, so if you can get the same result by playing around in photoshop than that may be a better bet.

What if it was as simple as adding it as an effect in the frame buffer for a post rendered scene? Sure, its just as easy to do it in photoshop but what about animations? Thats where it gets tricky.

Best for glow effects is to use more than 8bit brightness steps (for example very bright window and a white wall are approx. at the same brightness level at an 8bit image). But I'm not happy to save images as 32bit images, add postwork glow and save the image as 8bit. It need time and the 32bit HDR images waste the hard disk. A framebuffer postwork could based on 32bit (clamp output disabled) and the user could easy direct save 8bit images. Maybe the framebuffer could allow to use photoshop filters like XnView or other image software allow it. I'm dreaming ...

(The maxwell glow effects are frame buffer postwork only too).

Re: Glowing Rhino

vray glow materials isn't sufficient, especially glow transparency not works as it supposed to be
it just grays out the emit color instead making it transparent

so only option left is using translucency
