Title: Material node problem
Post by: Mac_Mac on 2018-10-13, 15:59:05: Hi there,
unfortunately I've found a serious problem with node materials which makes corona completely unusable for me...
Sorry for saying that but just take a look on these screenshots.
After saving scenes with materials created with nodes, while reopening them I loose connections betwen nodes! I have no idea what happens...
Also no textures are shown in textures manager...
I'm not able to manage complex scenes and find these issues...

Post by: Eddoron on 2018-10-14, 09:34:36: Huh, that's really strange. I have no clue. (rare)
I noticed that when using the CRN shared shader manually or automatically created, the undo function kicks out most of the connections.
Is there something similar in the scene?

Soon someone will tell you to upload the scene, so I'd already do that and when the devs are back on Monday, you might get an answer.

Hi,

I am really sorry but we can't reproduce your issue. This is a really serious bug and we would like to fix it so, could you please send us your scene? It can be very simplified if the issue persists. You can use our private uploader https://corona-renderer.com/upload (https://corona-renderer.com/upload).

Thank you
Nikola

files uploaded.
I forgot to mention, I've tested it on Mac OSX (Xeon MacPro) C4DR19 and C4DR20.

Hi, Is this how your node setup should look? If so, all I did was open your scene in R19 and R20, right click in node editor>sort materials. Everything was linked. I then closed the scene and re-opened and all nodes were still laid out as they were saved.
Title: Re: Material node problem
Post by: Mac_Mac on 2018-10-16, 12:43:21: I think some nodes are missing...
I attach how the nodes should look.
I'm on the B2 RC1 now and everything works OK.
Actually, your nodes are sorted different than mine...strange...

Post by: Nikola on 2018-10-16, 13:14:37: Thank you for the scene. I successfully reproduced it on my computer. It is strange that I can reproduce the problem that layer shader is split into two shaders only in your scene. I am trying to find the cause right now.

Title: Re: Material node problem
Post by: prildesign on 2018-10-20, 17:36:49: On a similar note, not sure if its been resolved / answered, but i'm unable to save any Corona Shared Material from the Material Node System to be reopened in another file... The only work around is then breaking it down into Cinema's native material system... something simple im overlooking? Id appreciate the help, cheers

Care to break down your workflow?

Post by: Cinemike on 2018-10-23, 20:23:10: Hope this (losing connections and duplicating) will be fixed soon. Makes using nodes pretty pointless.

Post by: sadece on 2018-10-24, 10:07:13: This happens when used Corona Shared. I fix it save and exit. But breaks every time when openned again.
Title: Re: Material node problem
Post by: Beanzvision on 2018-10-24, 10:49:13: Could either of you share one of your material so we can test it and add it to our bug report? Thanks.

Done.. In the folder is the text. "braided_wool_Diffuse_dif2" that was attached when I saved the project in C4D, but in the material I see no this texture.

I think I was wrong.. Seems like "Layer Shader" causes the issue.

Legend! Thanks a lot.

Post by: Cinemike on 2018-10-24, 16:18:08: It breaks the filter shader, too.

Title: Re: Material node problem
Post by: Cinemike on 2018-10-24, 19:38:51: Fixed!

Thx team!
Title: Re: Material node problem
Post by: Beanzvision on 2018-11-06, 13:15:43: Those that have been experiencing the "broken connection" issue, this should have been fixed in B2 Final. Could you please confirm that this is solved for you? Thanks.

Post by: stuart r on 2020-01-10, 12:26:08: I am still experiencing issues with the layer shader in version 5.
It's very odd as the shader network has multiple layer nodes but not all links get broken.
