I have been having some issues with getting the auto retopo going. From crashes to inaccurate results. Is the Sculpting and auto-retopo tools with 3D Coat a reliable solution? Does it compare to programs such as TopoGun? I have even tried non-merged geometry just to test, and still had issues. For example, goto New >> Voxel Sculpting >> Select the Man that is complete (first male character, bottom, middle) >> Under the VoxTree select "Mannequin Parent >> Right click and goto AUTOPO > AUTOPO > Click Ok. 3D Coat insantly locks up for me. Something like this would drive me crazy if I spent hours sculpting a model and I can't retopo it. Below are the settings I had before clicking ok. Does this lock up for you?

Regular installed gave an error during install. Manual install gave an error when launching the app inside of 3D Max. Both issues were fixed after running Max as Admin. It's strange because my account is set as "Admin", I'm researching now to see if I need to make some security changes. I'm just a home user, not on a work network or anything. Using Windows 10. By the way, the Retopo (Auto) option is working. Well done!

PolyHertz, Thanks for the update. This is the error I am getting when I launch the 3D App from inside 3D Max after installing and restarting: NEVERMIND! I resolved this by setting 3D Max to run as administrator! Sorry about this!

PolyHertz, First, thank you for updating this and maintaining this plugin. Huge time saver. Seconds, whenever I send an object from max to 3d coat via "Export Mesh for: Retopology (auto)", it opens 3D Coat, but nothing else happens. Its as if it only launches or switches to 3D Coat without any other action happening. It loads the geometry into the scene for all other options, but not Retopology (auto). Am I missing something? Thanks!

Has anyone had any issues where the geometry disappears when selecting the Sculpt room? My geometry looks fine in all the other tabs, but not in the sculpt room. It is totally missing. I do have "Show Voxels in paint room" checked on when in the Paint Room. Centering my camera also does not reveal my geometry.

I see it, it didn't make a difference cycling its check mark.

Hmm, I can not find a ""Show Voxels in Paint Room" button in the paint room. I did see the VoxTree tab under the Paint Room, but the eye was on here as well. WHere is the Show Voxels button exactly?

Hmm, I can not find a ""Show Voxels in Paint Room" button. WHere is this exactly?

Checking these options on or off has no change, my workspace area is still empty.

Question, when I switch to the Sculpt Tab, my geometry disappears. It shows up fine in the Paint,Tweak, Retopo and UV room, but disappears for Sculpt, is this common? What is the fix?

Thanks for this Ranger!

I have been using the ReTopo tool for a few days now and I love it. But I started researching the Auto-Retopo tool and I can not find a way to use it on a mesh that I have brought into my scene for version 4.5. I also try researching online videos and most of them are old, the procedures didn't work the same. Any suggestions on how to get started using the AutoRetopo tool? Thanks!!

Yeah, I even tried using 3d Max to create two UVs that used the same polygons. Works great, but when I bring it into 3D coat, it deletes one of my UVMaps sets. Even if I tell it to "Keep UVs" and "Import Tiles as UV Sets", it still deletes a UV set. Oh well. This is a problem when exporting for Unreal. Right now the workflow Im seeing is to unwrap and paint in 3D Coat, then when its ready, use a third party like Max to add the Lightmap UV. Then once its added, you can't bring it back into 3D Coat or you'll break the Lightmap UV. I'm surprised this hasn't been addressed yet in 3D Coat.

I can not figure out how to snap to the UV preview grid in UV mode. I'm trying to follow an online video to setup LIghtmapping in Unreal 4, but using 3D Coat instead of Maya for the UV Mapping. He indicates the importance of making sure your UVs start and stop based off a correct grid alignment, but I can not figure out how this is done for 3D Coat. Here is a link of where he uses this method in Maya's UV and the second he discusses this - https://youtu.be/-sJsR0y7R8U?t=8m1s Any suggestions on how this is done in 3D Coat?

Nah, it appears they are using 3rd party like Maya as a work around. No real solution appears to be in that thread. I'm assuming its not possible yet. If ever. Is that accurate?

Ok, I'm trying to create a second UV Map in 3D Coat that effects the same geometry, but for Unreal Engine LightMap. Apparently in 3D Coat I can only have a single polygon on one UV Set, and not another. Thus, I can't create a lightmap for Unreal using 3D Coat. Any solution to this? Yes I know I can do it in a third party program like 3D Max, but I'm looking to do it in 3D Coat. Thanks

I've got it working now. Having "AutoUnwrap" instead of "Keep UV" was compressing everything into a single UV Tile. Thanks guys for the feedback!

PolyHertz, Thanks for the screenshot! That was the problem I was having. I was not clicking the "Open in Original App" link. I didn't even notice it. This works fine now. Great script! Thanks for sharing!!

Sorry, Im using 3D-Coat 4.5.19 and 3D Max 2016. I'm exporting as a obj with multiple objects selected. Each object has its own ID number and own Material assigned to it. For example, 4 separate ceiling pieces have IDs 1,2,3,4 and 4 different materials assigned. When I import the obj into 3D Coat using the "UV Map Mesh", my "Paint Object" list has all 4 objects listed correctly. My "Surface Materials" list has all 4 materials listed. But my UV mapping window has ALL objects sharing the same UV Tile. How do I separate each object to have its own UV tile? Thanks

Hmm, I didn't chose an export option. When I was finished working in 3D Coat, I went straight back into Max and clicked the "Import" button on your Max plugin. I assume I have missed a step. Perhaps I need to add your script somehow to 3D-Coat as well? Because my only export options under 3D-Coat's "File" are "Export Objects & Textures", "Export for Steam", and "Export for 3D Painting". Do I need to install something for 3D Coat as well?

Polyhertz, First. Thank you for doing this. This is great. But the only problem I have is that the "Import" button does nothing for me. I can export to 3d Coat just fine. It even opens a close 3D-Coat. But clicking "Import" does absolutely nothing. Any suggestions? Im on 3D Max 2016 and 3D Coat 4.5.19 (CUDA 64), Windows 10. Thanks!!!

When I import an obj file that consist of multiple objects, 3D Coat uses the same UV Unwrap on ALL the objects. How do I get 3D Coat to recognize each separate object to have its own UV Unwrapping?

Im very confused why a third party script is needed to move geometry from one section of 3D Coat to another. Why doesn't the developer allow this to happen inside the application itself?

I imported a model I created in 3D Max, works fine for UV Unwrapping, works fine for painting. Entirely missing when I select the "Sculpt" tab. Any reason why? The model is a fishing dock and I want to use the sculpt tool to change it up a bit.

Digman, Thanks for the feedback on this.
