3ds max doesn't render with gpu
show user profile  TheShaps
Hello guys!
As you can probably tell I am very new to the cgi world, and the 3ds max world.
I have intalled 3ds max 2015 and vray 3 (latest version) on my pc. I am using win 7.
My gpu is Nvidia gtx 770 2gb .
I am rendering with the vray adv engine, I have noticed whenever I hit the render button(f9) my cpu usage is going up insted of the gpu . I have tested the gpu usage with the analytics software Msi afterburn. Also I have blender software installed and whenever I render there the gpu usage does go up.

How do I enble the gpu rendering.

you use a different renderer, vray RT is probably what you're looking for

Dear Mr. Shaps, you need to educate yourself a good deal more.

Ok, I now understand that the RT engine is for gpu rendering , and the ADV engine is for cpu rendering. However there is difference between the gpu render and the cpu render in the RT engine. The gpu Render dosent render the vray materials I have assigned to the object, but if I switch to cpu rendering it does render the material properly.

Is there a way around this problem? I want to be able to use my gpu, but also use vray

technically, RT isn't for GPU, its just capable of using a GPU whereas the other one isn't. Anyways, I'm not a vray guy but from my experience the materials should be cross compatible, you're probably running into memory limitations or whatever, try lowering the gpu map size. You'll run into this a lot.. gpu side rendering isn't really practical for now.

CPU is still king for Rendering these days I believe. There are some good GPU renderers out there but they tend to lack features compared to CPU. There are also some Hybrid solutions also but these don't necessarily perform as fast as you'd expect.

For correctness: Cycles has exactly the same features on the CPU as the GPU, and with a 4GB card, I've only managed to hit the limit with really high numbers of objects and textures. For most of my renders, they fit into 4GB.

That's true Nik. But cycles is lacking features compared to commercial packages like Vray I think.

So you guys are telling me that most renders are cpu renders? I have heard that the best render engine is vray, and that's what most people use, its kinda hard to believe that most renders are done with cpu. Do you know any better engine that supports gpu and is good as vray? In any case I think I have found the problem causing the incorrect material rendering, simply the Rt doesn't support allot of features as of yet. Source:

TheShaps, technology is not as far along as you may think. Most operations in 3D packages are still built to use only 1 core. And most production renderers use the CPU. There are a few exceptions to the rule which may benefit you in some way... Houdini - multithreaded particle/voxel flow, gpu rendering (Mantra). Blender has a CPU/GPU renderer as Nik mentioned. Vray RT is still primitive and buggy - But good enough for "basic" scenes (essentially whatever is in the supported feature list). Redshift/Octane are popular GPU renderers.

I would like someones review on Modo (cough* Garp) to detail their experiences with the multi-threaded/gpu nature of each operation.

MODO 801 still has performance issues in areas like dynamics, deformations, UI responsiveness, etc. And the renderer is still 100% CPU. So maybe not the best example.
Now, 901 went out today (this afternoon) and according to the presentation, there are substantial improvements all over the place. I won't know first hand since I don't plan to upgrade before SIGGRAPH but I'm gonna keep watching very closely.

Anyway, it seems we are finally reaching that critical mass where things become easier. The trend is definitely there: frameworks and libraries, textbooks, courses and conferences. Plus the influence of programming for both small devices and warehouse computer systems. All that hard research is starting to pay off.
We should also see interresting things in hardware. AMD have been working like crazy to merge the two technologies inside a single chip.
Interesting times :)

Max shippes with the iray renderer from NVIDIA that is GPU based and it supports most of the mental ray materials in 3ds Max, but not the old-school materials. There are however also some special materials for iray available for free, that are based on the new MDL system from NVIDA. MDL = Material Definition Language. Download here:

You can also render the AO pass (Render Element) on the GPU when using mental ray.

The QuickSilver renderer do also add GPU, but it is very limited. It is pretty much just the same engine as the viewport, but it could perhaps be used for qick rendering previews.

NVIDIA are also working on a GPU accelerated GI-method, a prototype of it is available in Max 2015, read more about it here:
There's an interesting example in that blog post with an image's render time squeezed from 13 HOURS down to only 37 minutes! But only under certain circumstances.

vray is certainly very popular... you'd be hard pressed to find an argument to definitively call it the best though

This is partly true of max, but not many other 3d apps are so limited
