vray dirt support bent environment and other modes

[Morbid Angel]

In mr a very useful feature in amb occlusion is ability to output following modes:
reflective, bent environment, bent environment tangent.
I would like those options to appear in vray's dirt as well.

Jup, the vray dirt is missing some basic features, coincidently I was just rereading these threads right before seeing your new thread.

I don't know man... reflection occlusion (in the non fast Raytracing world) makes sense. But to be honest, I used to use AO and RO a lot when in renderman understandably. But once you move to Vray, and you really look at what it can do, you really don't have a need these in the same way... especially that tutorial that Turtle is showing... Just do a REAL reflection that bounces light. The domelight makes most of these hacks no needed. Vray's domelight is the BEST IBL system I know. True IBL. No need to make a convolved anything. Just use a high res, very high dynamic range image... and you have the best IBL system around. Now I am not saying AO and RO are still not needed, but the approach is different. The big reason to use them is to integrate things into a plate. But you need to approach these thing differently. Use a 100% white diffuse shader with the true HDR and the domelight, and you have a perfect shadow pass which includes the ambient light. Make the object 100 red and you the equivilant reflection model on the plate, you you have the exact refl occ of the object on the plate.

well for rendering yes. My purpose was something else: i needed to bake this into tex map sequence to be used as a normal map.

Right.... so you need it for a specialty utility map.

yeah i mean for example in my case i have a very detailed cloth that i cant really use in a shot, so i need to bake that sequence as a normal map and use it as a map but i cant
