Mosaic based texturing resulting in blurred triangles on scanned models and how to rectify this.

Hi,

I’ve been noticing for a long time that the textures on my models are far better quality with mosaic based unwrap enabled but quite often, almost always in fact that is also met with patches of what appear to be out of focus texture mapping and I was wondering if anybody has figured out a way to rectify this without merely cloning areas of the textures maps in Photoshop/Gimp?

Maybe there are tools in RealityCapture that enable you to select the blurry triangles and either view the cameras that are projected onto that part of the texture map so that you can then turn them off for that part of the texture, specifically for those triangles would be incredible, or if there’s any other work around inside the RealityCapture UI that I’ve not yet found at all?

The issue doesn’t arise when using the geometric based texturing / unwrapping but obviously there are significant differences in the overall texture quality when using this method.
Here are some images to help illustrate what I’m talking about.





As you can see from the sequence of progressively zoomed images, the areas of high sharpness when compared to the patches of blur are drastically different.

My workflow after scanning consists of cleaning and manually unwrapping the models in blender then reprojecting the textures in RealityCapture but obviously the reprojection comes from the original scan textures so inevitably results in the same blurred patches.

I’m sure there has to be a workaround but this smooth brain of mine is yet to find it. lol

Any help from you guys with nice wrinkly brains would be greatly appreciated!

Thanks in advanced,

Hi Jack,
I think this issue is the same as mentioned in this post: issues with mosaicing unwrap method / texturing style
In general, the application doesn’t know if the image is focused properly or not. It takes the image, which is most suitable for the area and in your case it is the unfocused one. The only way to make this better, is to disable such image for texturing. I am sorry, but there is no other option, yet. We are still working on the improvement of this feature.
