V-Ray 3.0 for 3ds Max Beta Open!

[vlado]

Here are some quick differences, but I used directly the images from the web site, so I don't know how valid this is (good that they are PNGs).

As you can see, there are some differences. I expect there to be - so much code has changed and the noise is also very likely to be different. Still, seems very close.

Then it would be interesting to try it See here: http://help.chaosgroup.com/vray/help...tem.htm#embree

Yep, me too

Best regards,
Vlado

I shall give it a try and post results!

Heya

Thanks, well 8 bit image is really bad to do it on but o well

Yep, I agree. Hopefully Simon will get to do proper 32-bit ones.

The speed increase on the glass render is unreal!

The 3.0 render has a lot more noise than the one from 2.4. You can clearly see that on your images.

The noise levels are in general different, yes. I've tried to explain it here: http://help.chaosgroup.com/vray/help...htm#bruteforce

But, on the one hand, in one case you are faced with a 1h render and no way to go lower, and in the other with a 13 minute render with only slightly more noise that you can clean up if you need. People specifically wanted faster glass renders, so I do faster glass renders...

I will re-run the glass test to double check!

Oh, okay. Didn't see it yesterday, sorry. What would be the best way to get the two images to comparable noise levels?

Increase the AA settings a bit. That's all.

Sorry for the dumb question: Using the new shading rate parameter or via min and max settings?

If it's not a glossy material, the shading rate will not affect it. You can modify the min/max subdivs (and maybe the color threshold, I don't know what it is set to in the scene). Basically in the same way you would normally deal with noise in V-Ray.

Thanks for the clarification, Vlado. Seems to be easy to clear up the noise, then.

Hi Chris,

Thanks for the reply!

RE: Purchasing a new Vray 3.0 instead of upgrading an exsisting 2.4:

Hi Michael,

For us this is not a problem at all - again we are not here to force to do anything, we choose what's best in your situation.

Here I feel you (wrongly) assume that the compatibility would be 100%... If you use V-Ray 3.0 to create a scene and try to use V-Ray 2.0 to render it (assuming it is really possible), you might face some serious compatibility issue.
The opposite is more likely to supported. And you are right to mention that the base cost of a new V-Ray license is going to be cheaper
Ultimately every user have different situations and concerns. If in your case the option to buy V-Ray now and receive the free upgrade to V-Ray 3.0 with 3x RN sounds a better deal, then we would be more than happy to help you in this process.

Wow. This is pretty crazy! I do struggle to think why anyone would want to upgrade now! I will definitely buy a new 2.4 licence in this case (for the free ugprade path). The current 2.4 -> 3.0 upgrade is a definite 'downgrade'.

But a new Vray 3.0 with the 3 render nodes sounds ace. Great!

Thanks for those render tests @ askhamdesign. But I'm confused wasn't the render speed increase supposed to be brute force only? So why the big increase with using IR as primary solution? (Not that I'm complain)

The changes affect other situations too, not only and specifically brute force - although they are indeed more apparent if you use brute force, especially with lots of bounces.
