Title: Displacement with AO crash
Post by: Nuno on 2018-09-18, 11:18:06
Hi everyone.

I've noticed a consistent crash after I create a material with displacement and add AO to the layer list.
So, what I am doing is as follow. I go to texture add  layer, then go to shader and add a noise, then after that I go again to shader and add a corona AO. Every time I add that shader c4d crashes.

Is this a limitation, bug or is still a work in progress?

Thank you
Nuno

Hello, can you attach you material here so we can test it?

I can't, it crashes every time I do it ;) Just try do this, add a layer in displacement (texture/layer) then shader/ Corona/ AO. It just crashes. Attached is the error message

Also noticed that I get random crashes rendering with several displacement materials. Also cant get the c4d file as c4d stops and never automatically quit. I have to force quit every time :(

 Thank you

Exactly!

I still see also a lot of, apparently random, crashes when using displacement. Can't tell exactly what is causing it, I do know that for those crashes are not related with the AO thing :s
Unfortunately I cannot share the c4d due to NDA...

Thank you

Ok, now it crashes every time I try to render view... But, if I render to picture viewer it not crashes... that's is a pity... :( although is still "workable" but not perfect.

If there is anything that I can provide from my side please let me know.
I think that the bugreport txt might help the dev team to troubleshoot. I will attach it to this post.

Make sure you are not using any third party plugin with your objects...!
I am having experience of crashing with Maxon Parametric Tools.

No, I am just using c4d and corona. No plug ins are in the scene.

edit: also everything in the scene (3D objects) are editable. So nothing is parametric.

As I do.... I start removing some objects and see renders and adding some more objects and see... I hope you will find out where it is crashing.
And give a try one with override material, I mean remove all material and use only one default material.

I know what is causing it, is displacement. If I disable displacement the problem disappears. ;)
Now, sometimes it renders and most of the tries just crash after crash.. :(
