Vue6-Xstream / vray / mentalray ?

[mmikee]

Just for the record, I was only comparing workflow when it comes to
calc lighting for the nth frame. Not the methods.

for me...no qmc gi in mr, no gi at all.

Sure opactiy mapped leafs are slower than mesh, but with the dropped setup they are not too bad you know. no blur/filtering off..etc..etc..

well we ran into problems with max opacity levels. Had to really crank it up for certain scenes, which just further murdered the render times.

[Morbid Angel]

I think its time for vlado to think about some clipmaps. In lightwave you can specify instead of opacity a clipmap which will basicly overlook the polys in the spcified area, kind of like displacement clipping, but for regular geometry. Resulting in a fast render time, and none of the problems you guys are facing.

Ah,

thank you all for your input. So most important is , Vue is looking for an implementation of Vray, as one of you has posted here as a statement.

point is , vue seems to do increadible results when it comes to large area animations with lots of trees.

but when i see the results of architectural implementations, it seems, the overall quality of trees, and light is rather poor, compared with vray.

nevertheless, we will have a try and look if there are any acceptible workarrounds so maybe we can the good points together.

thanks for all your answers...



oh by the way.. what is this, irradiance. animaitons support for deforming meshes...

Well the current IR map is pretty bad for animated objects/mesh, you generally gets lots of flickering and splotches.
There is a new IR method (in the unleased RC's) which is much more suitable for animated objects/mesh.

[Morbid Angel]

yeah what daforce said...basicly you calculate your irradience map as usual, then it will interpolate the irradience map between every frame and see how the objects change and try to adopt to it. I think vlado has posted some examples in the announcement section.
