Problem

Description:

Rendering ornatrix hair causing huge artifacts while rendering on Backburner.

Fur renders normally when:

- Rendering on local machine as a sequence or a still image

- Rendering on backburner as a single frame

- Rendering on backburner as a multiframe render but started half way through

Fur doesn't behave properly when rendering as a sequence on backburner from the beginning.

The results of the hair causing artifacts are shown in the images, a working result is also attached.

Do you have any idea how to fix this?

I have remade the hair several times and changed the animation of the mesh but get the same problems.

Steps to Reproduce:

Newest version (not beta) of Ornatrix, 3ds max 2014 and vray 3.0

The hair is on a PointCached mesh which was previously skinned and used morph targets.

Modifier stack is as follows:

VRayOratrixMod

Ox Render Settings

Ox Strand Clustering (Group controlled clustering)

Ox Hair Clustering (Map to control clustering)

Ox Strand Frizz

Ox Strand Detail

Ox Strand Length (map controls length)

Ox Hair from Guides

Ox Edit Guides (I have created a group with certain guides selected to control clustering)

Ox Strand Frizz

Ox Hair from Guides (To create more Guides from existing Guides)

Ox Edit Guides

Ox Guides from Surface

As further detail I have attached a video showing the artifact, it seems as if some of the hairs from the elbow are connected to the knee joint perhaps?

Hello,

Are you using the Remember Button in the Hair from Guides modifer? If not you should render a single frame first, then click Remember, then submit to the farm.

Thanks

Michael

Hey Michael,

Thanks for the fast reply, that doesn't seem to work. Still getting the same repeatable result that I've shown on the video.
