Hi! Can anyone give me a step-by-step gide for masking out unwanted areas to the external file?

What about the file naming conventions and does the info need to be in RGB or in Alpha of the external file?

Why the external file?

Sometimes I have a need of reexporting raws with different setup for calc and for texturing, but I whant to make alpha only once.

Looking forward to hear anyone :)

  Hello dear user,
  I would like to first mention it is not always good to mask your images. Sometimes the background is very useful for alignment.
  Although, if you really want to, then you can do so in the RGB channels of the file with a black, white or any solid color. As solid color cannot get recognized as points in space.

  Thanks for the reply.
  Is there any naming conventions for the mask file so the program could recognize the mask?
  For example
  DSG5467.jpg
  DSG5467_mask.jpg

  If you want to use the yourself created mask as a separate file recognised by RC then it should also have the information in Alpha channel. First I thought you wanted to mask the source files directly.
  
  RealityCapture can automatically detect these types of layers:
  
  .geometry (equals to image/folder with no layer extension)
  .mask
  .labels
  .depth
  .textureXX
  .texture (equals to .texture1 and .texture01)

  NOTE: Instead of dots (.) in the folder names, you can also use one of these symbols: _ @ # and !. For example: _texture, @texture, #texture or !texture.
  
  The mask in your case should look as DSG5467.jpg.mask.png

  Wow, thanks, that's the clearest answer I've got so far! Will try it a little later.
  A mask has to be *.png only?

  Pleasure is mine. I don't think it has to be, but I would recommend you to use it as such, due to .png having low file size and providing the transparency.
