Mantra - Roundededge Node

[Chillkroete 0]

Why is the roundededge node so buggy?

I want to use the node as alpha in a layermix node.
When i do so, i always get a message the my pc is running out of memory (i have 128gb ram).

Somebody any solutions?


kind regards

i use it quite frequently and it works fine for me. not sure what are you trying to accomplish in your setup, however what i can see at the image doesn't make much sense to me...

I´m using the node tree as alpha for my layermix and as alpha for the displ._output.

As soon as I use it for the displ._output i get an error message.

i can't really see what's going on there... something is definitely screwed up in your setup. can you post the file?

ok the thing is that displacement is evaluated first and then edge detection is performed (as it takes a new geometry created by displacement into account). easiest solution would be to A: bake the mask into a texture first, or B: do it in SOP level and bring it into the shader as an attribute.

Thank you!

I turned "True displacement" off in the material builder - is it still calculating a displ. or just bump?

A: I have to use the bake texture node in the out conten to create a texture of the mask, am i right?

B: The geometry is unfor. to low poly i think, isn´t it?

C: Is there any other solution for this problem?

True displacement off means just bump. I suspect thou there is still displacement calculation going on if it is plugged into displacement (not sure by that, you have to test it).

A: that's right

B: yes current geo doesn't have enough resolution. if you can't subdivide to get enough resolution you're left with option A if you want to stay in houdini

C: other solution would be to use texture painting software

Ok, thank you very much David for your help!
