Title:MeshFromStrandsNode - map channel error
Category:Crash/Critical
Status:Open
Posted By:engineeringa52 ( Kevin Bass )
Date Created:22 September 2016

Problem

Description:

I am getting an error when trying to create a second mapping channel using the MeshFromStrand node.  I mentioned it in the other thread, but am adding it here so you catch it.

1. make sphere

2. apply feather preset

3. change mapping channel

4. error

I cannot reproduce this. Just to be sure we're on the same page: created sphere, put quick hair (feathers), and in MeshFromStrands changed "Selected Map Channel" to 1. Does not error for me. Which ornatrix version are you using?

Strange, I'm doing the exact same steps you did and cannot reproduce it still. Can you please try with a newer build (nightly 1.0.9.8745 for example). If you are able to test with maya 2016, that would be great too.

26 September 2016

I iwll try a new build.. but I cannot try 2016 as we are skipping that here and moving to 2017 but we do not have 2017 prepped for our pipeline yet.

standy by.

any progress in re-producing it?

we are on Windows 7/ Maya 2015 ext1 sp 6 and i've tried with the latest stable and latest nightly.

thanks

Hi Andy,

I notice in the video you are doing a lot of extra steps besides what you wrote in the original description of the video. If you just set the napping channel count to 2 right after applying the Feathers preset do you still get the error? I've been trying to reproduce this here without any luck.

yeah still happens.  I have a funny feeling that it might be a hardware issue as I feel that this worked in earlier build on a different machine.  I was reciently upgraded.  I am trying to get on a different machine and test it.

this was litterly 3 steps.

create sphere

click feather preset

change map channel.

Strange indeed. I checked the code where this assertion happens and it seems given the same steps it should produce correct results. Being able to reproduce this would certainly help a lot.

different machines... also we do not have a local install we are using a module with the unzipped archive.

hope this helps...  in a few mintues i'll install locally and see if that fixes the problem.

I'm also getting an odd behaviour with the surface comb node as there are no created feathers until i put a few sinks there....

 

i seem to get a proper extra map channel when i:

delete the surface comb, MeshFromStrands

create new MeshfromStrands

change map channel.

this is a local install now but i saw the same behaviour with the network install.

thoughts?  it feels like there is something wrong with the surface combNode??

I'm finally getting it to work but I also had to click "remember root" positions in the HairFromGuidesNode node.... is that a requirement for the map channels to work?

Very strange, it is almost as though the preset is different or something is being evaluated differently. I will test with the exact same build and let you know what I find.

hey just installed 2017, i've been busy on other stuff but I finally had time to come back to this.  again... still getting a map channel error.  

simpley create sphere.

use feather preset

change map channel count

no uvs in either channel when checking per-strand node.

 

here is the error

The error you're getting now is different from the one in the past. But I could not reproduce it (Maya 2017 on Windows). After opening Maya I created a sphere, added a Feathers groom to it, clicked the MeshFromStrandsNode in the stack and changed Map Channel Count to 2. Here's the log from the Script Editor:

CreatePolygonSphere;
polySphere -r 1 -sx 20 -sy 20 -ax 0 1 0 -cuv 2 -ch 1;
// Result: pSphere1 polySphere1 //
OxAddHairToSelection;
// Ornatrix: Ornatrix 1.2.0.10430 Release initialized //
select -r MeshFromStrandsNode1 ;
setAttr -type Int32Array MeshFromStrandsNode1.mappingTypes 1 0 ;
setAttr "MeshFromStrandsNode1.mapChannelCount" 2;

any ideas on how to trouble shoot or get a better log to you guys?  can you get me a debug build so i can give you more information?

thanks

Problem solved.  We selected a different mapping type then back to the first one... and it works.  but only if you have Per-Strand Coordinates checked for the first mapping channel otherwise the mapping for the unlying surface gets garbled onto the feathers.

looks like there is an underlying refresh of the node that i not working correctly.

Also the base channel index is randomly getting different values automatically put there... FYI
