Summary

Title:	surface comb sinks not working correctly on custom geometries
Category:	Workflow
Status:	Fixed
Posted By:	l2ezad ( reza dehghan )

Problem

Description:	when you draw the surface comb node sinks on a custom geo , the sinks don't follow the model surface correctly , and intersect with model often. so the comb direction will not work as it suppose to. also i tried to edit the sinks after i created them and make their position better , but the snaping function it has , will not allow the sinks to follow the surface correctly.
Steps to Reproduce:	import/model a custom geo add ornatrix hair add surface comb add sinks and draw on the model

Jeordanis Figuereo	Hello, Thank you for the report. We are looking into this. I will keep you posted about our progress. Can you provide your scene for testing? Sinks are working fine on primitives but not on custom geometry as you noticed. Jeordanis Figuereo (Product Designer. EPHERE Inc.) LinkedIn Discord

l2ezad	here you can test it on the bird . also with this scene you can check the scale problem i've reported on another topic. and i have to say , i used latest built for testing these . Attached Files: bird02+r19.c4d (538099 bytes),

rsodre	Hi l2ezad, I think I solved the main issue with the sinks problem, the fix will be on the next build, but there's something on your project that is no quite right yet. Looks like your project plane is rotated, it is standing up. On your project, it is parallel to the bird's body. If I copy everything and paste into a new project, the plane is like it usually is, and perpendicular to the bird's body. The screenshiot shows this with the body isolated. Is thre any settings you changed on the project axis plane? I didn't find anythong to set this. Roger Attached Files:

l2ezad	nope , i didnt change the planes , however , i transfered the model between the cinema 4d and zbrush via GOZ plug in , and as i know this may change some of the settings. and main cause of the axis plane problem.

rsodre	I found the problem, it's related to the project's workplane, which is rotated. The fix will soon be available. Roger

rsodre	The fix has been implemented and will be available on the next build. I have something to comment about your scene. The bird has a scale of 0.01, so you may be trying to scale Ornatrix hair up 100x. This will cause some problems, specifically for hair interpolation (guides will be too far) and widths (will be scaled up 100x too, messing up the hair shader). I suggest manually set the object scale to (1,1,1), then use the scale tool in Model mode and scale it down again. The tool will not affect the transform when in Model mode, it will shrink the polygon triangles, so you can work with the object on a natural realistic scale and avoid those problems. Roger

l2ezad	thank you for youe comment roger , will try to fix my scene.
