Texture Masks

Hi,

is there any way to use masks for texturing?

I explain my problem: I have two sets of images of the model. One set with lots of overlapped photographies but with bad illumination, and the other one with a few photographies with good illumination but bad overlapping. I’m using both groups for alignment and mesh generation and only the second one for texturing.

However, the overlapping on the second group is so bad, that there are some small parts missing. I know best solution is taking more pictures with good illumination to cover this missing parts, but this is not possible.

So, I thought to use some of the bad illuminated photographies to fill these parts. But, although they fill this missing parts in a relatively good way (after some postprocessing of the images), they make other parts worse: parts that were very well represented in the second group starts to have noise or even important changes in color.

I have tried visibility-based and photo-consistency algorithm and the results are very bad in both cases. So, I can only imagine some texture masking to solve the situation. But, as far as I know, masks in RC only affect to alignment and meshing… Is that right? Any other idea?

Thanks!

Dear Imanol,

you are right, masks are in RC used just for alignment and meshing.

What you can try, is crop your worse images into the wanted areas, import these new cropped images into the project and use them for textures.

Also, you can try change the weight for texturing for this particular images.

Hi,

thanks for asnwering so fast. That’s a pitty that there are no implementation of masks for texturing… 

I will try croping them but then I’m limited to squared shapes…

I have been tunning the weight also, and the results improve but not so much… What are the usual scales to choose?

Thanks!

Hi, it is up to you, there is not usual scale for this. Set the value lower than 1 to decrease the impact of the selected input(s) in the coloring/texturing process.

Just to bump this thread, are there any plans to implement using masks for texturing?

Hi Burgschneider, there is a feature request for it created.

Super!

Is there a link to the initial request or somewhere where I can follow the development of this?

It is in our internal database, so there is no link for that. If the feature will be implemented, it will be mentioned in release notes.
