show user profile  Alex910
Hello, how can I set 3ds max to use hardware acceleration when rendering?
Is any setting there or i have to download something for that?

Thank you;)

Scanline, mental ray won't do this. You need iray, or the version of Vray that supports gpu rendering.

Which renderer are you using?

@Nik- Are you talking about Vray RT or does the standard, production (not activeshade) vray have that ability now and I'm behind the curve on things?

Vray RT....

Also...in general,...GPU rendering is not the holy grail,...not "everything" is supported, and you DO need a kickin gfx card! You might also find if you have say...a GTX 580 or so and some kicken cpu's (2 X 6core) that the CPU is faster anyway!

Personally, I am impressed with iray.

This image rendered in three minutes on an i5 machine with an Nvidia 560. A real budget system.

Some things i find limiting though Nik. Unless things have changed recently, i didn't like the lack of things like being able to use blend materials and lots of other little niggles that escape me now! :)

That hasn't really changed, sadly. Pretty much all the things I'm used to in mental ray don't work in iray yet. It can be quite infuriating at times. It has improved over version 1, but not as much as I'd like.

Yeah, had a feeling that was still the case. It is a shame, i'm sure that it'll improve in the future though. I guess its early days.

My biggest grief with them is the fact that everything has to fit in the gpu memory which basically means that all things furry (hair, grass, foilage) are out. They could stage the buffers to the main memory for extra space but since memory space is the only remaining selling point of quadro/tesla cards (iray is owned by nvidia in case anybody forgot) i doubt that will ever happen.

fur shouldn't take much vram, it's procedural.

Yeah. it's quite limiting, especially on my 1GB card. Main memory is fairly fast, there must be some clever programming trick they can come up with.

This is about what my 1GB card can do. Much more and it falls over. This is without textures.

you can access main memory from a modern gpu but there's a performance hit & software isn't always configured to use it. on top of that you can rotate stuff in as you need it but again with a performance hit. that's why amd is moving to a unified memory architecture.

Well, it's a shame. I wonder if the perfrmance hit outweighs the advantages. Unified memory, hurry up. Although I dont' think Nvidia will ever let ATI cards render iray.

It is to me. To have an unbiased render that works with my mental ray experience is awesome.

Each to his own.
