Daz consistantly crashes when in geometry editor and removing surface groups. After Decimate and Tex

kapynvne_328bc2e563

In order to take a Daz character into Unity3D I have to first decimate it and then use the texture atlas.

This creates a lower poly character with a single texture.

Unity 4 shaders require at least two surfaces: one for diffuse shading and one for transparencies.

Because the Cornea, eyelash, eyesurface and tear have no diffuse color can be kept separate from each other.

This means I can combine the following into a single surface called "Body": (X not included)
1_EyeSocket
1_Lip
1_Nostril
1_SkinFace
2_Nipple
2_SkinHead
2_SkinHip
2_SkinNeck
2_SkinTorso
3_Fingernail
3_SkinArm
3_SkinFoot
3_SkinForearm
3_SkinHand
3_SkinLeg
3_Toenail
4_Gums
4_InnerMouth
4_Teeth
4_Tongue
X --- 5_Cornea
5_Iris
5_Lacrimal
5_Sclera
X --- 6_Eyelash
X --- 7_EyeSurface
X --- 7_Tear

(Eyesurface and Cornea can usually also be combined, even Tear to bring the final surface count to 3 or 4.)

I do this by selecting those surfaces and assigning them to a single either new surface or on of the existing ones that I rename to body.

This leaves 22 surfaces with no assigned polys that I need to delete.

When I right click the surface and select "Remove Selected Group(s)" Daz crashes.

It only crashes if the character has been decimated (or lOD added).

I've tried this on 4 separate computers and it crashes at the same time on all of them.

--------------------------------
Reducing unnecessary surfaces is essential for unity performance because it reduces draw calls.

On a related note : ( I know the following is a known bug, any idea when it'll be fixed?)

Texture alas also produces some fine "seams" depending on the texture used, which look ugly and have to be post-edited.

Is this the current production build (or even the current public beta)? If not,. try updating - there was a crash bug with deleting empty surface groups a while back. If it is, please bug report it by opening a Zendesk ticket for Technical Support. In the meantime, if you export as OBJ do the empty groups even appear? If not then you don't have to delete them, except for tidiness (which isn't to say the issue is acceptable).

I've noticed this occurring for a while but its now a big issue since I started working with Unity.

It occured in 4.6 possibly before, it still occurs in 4.7 and 4.8beta

The exact versions I've tested right now are : 4.7.0.12
and
4.8.0.9 (Public build)

Both are the current builds.

I have submitted a bug report here :

https://helpdaz.zendesk.com/requests/new

I assume this is the right place because I google searched and couldn't find anywhere more appropriate or a form labelled "bug tracker"

That's right, just open a support ticket for technical Support. That enables them to deal with non-bugs that just require information, and to pass the actual bugs on to the developers. When there was a separate bugtracker it got issues that were really support requests and vice versa.
