Corona Renderer 5 for 3ds Max - Daily Builds Discussion

[rowmanns]

Hi,

I have discussed the GPU compatability issue with the new version on Optix with our dev team.

Unfortunately for people with Keplar generation cards we will not be rolling back to Optix version 5.x.x. For the time being we will be sticking with Optix version 6, and at somepoint in the future probably moving to Optix 7.

We are going to look into a better way to detect what GPU is in the system so we can check if it is supported by Optix and provide a more descriptive error message.

I hope that this information is useful, and I'm sorry for the inconvenience that it has caused.

Thanks,

Rowan

Ahhh, shucks. Progress before compatibility I guess. Either decision is a good one :]
Just FYI, according to the Steam survey, the 750ti is still in the Top 10 most videocards used.
Just out of curiosity, is there some hidden "replace this file" and change this .ini setting to enable zombie backwards compatibility held together by tape and bubble gum - only for the adventurous Corona-nauts?

hey guys - ive got a gtx 1080 and im getting the optix error - this gfx card is compatible right?
So far ive:
got the latest 1080 nvidia drivers installed
reinstalled corona and the denoiser.

Am i missing something?

No GPU denoising for me, then. So sad.

Hi,

Which error message are you getting?

Thanks,

Hi,

I'm sorry, there's no way to do this :(

Curious to know more about new displacement mode. Does it has some limitations compared to the old one? I did super quick comparision test and found that while 2.5 mode offers impressive speedup, RAM savings and has more details, it also shows quite strong artifacts all over the place.

Hi

I cant remember exactly but it was regarding optix and missing optix 6 DLL.

Hi,

To me it looks like the displacement is much finer with the new displacement enabled rather than artifacts. But it is a little bit difficult to tell.

Would you be able to provide me with the screen size (px) you are using for both the new and old displacement? And if possible would you be able to send over your scene?

Cheers,

Rowan

Hi,

It's a little difficult for us to debug it without the full error message, next time you encounter it would you be able to send it over to us?

Thanks,

The artifacts are best visible when you alternate between the pictures - look for dark vertical lines in "displacement-new.jpg".

Render settings were completely default, it's just a plane primitive with Corona material and procedural noise in displacement. I didn't save the scene, but it should be very easy to reproduce. I'll try to make some more tests later and see if i'll be able to get more pronounced artifacts.

Edit: here's more convenient comparison: https://cdn.knightlab.com/libs/juxtapose/latest/embed/index.html?uid=781777ee-e444-11e9-b9b8-0edaf8f81e27

Hi, can you show us how your mesh topology looks like before displacing?

[romullus]

It's default plane primitive with 4x4 segments, not even converted to mesh.

Very best new corona displacement!

Does 2.5D Displacement fully replace the old method?
Is there any reason or scenario to use the old one except compatibility to old scenes?
