I remember unwrap button and now couldn't find it . Where it is now?

Also how can I set a target texture resolution for  texture re-projection?

Would be appreciative for any help

  Dear kir238,

  the Unwrap button is in Reconstruction tab/Model Color and Texture/Unwrap

  

  When you click on that button, it will open the Unwrap tool, where you can set wanted parameters:

  

  During texture reprojection is used original texture, which is reprojected on simplified model. You can set the texture resolution during texturing detailed model and then reproject this texture to simplified model.

  Thanks Ondrej.    when  you say original texture  do you mean the texture of  re-projection target object it had been saved with in 3dmax or something?

  Or you mean  some settings in Reality capture itself?  

  For example I have 20 Udim 2048x2048 textures in Unwrap settings  but while re-projecting I get single 8196x8106  one.   Where it takes that 8196 ?

  I meant the one created on bigger model in RealityCapture, which you want to re-project to smaller model.

  It could be in set in Unwrap parameters (Unwrap tool)

  I did "unwrap" for hi res model with 20 textures each 2048  and still getting one 8192 ( as I unwrapped it in Blender)  texture after re-projection.    

  Do you mean I need to unwrap low res in Reality capture too and set size in this another unwrap settings ? What if I want  the same unwrap I did in Blender?

  I found "imported model default texture resolution"  in another settings line. Is it there?

  set it to 16384  but still getting 8196?

  Also I wonder if Reality capture uses edited vertex normals  of imported low res   for re-projection ray direction/vector ?

  What I know, there is no possibility to export non square textures.

  To your second question, no it is not possible. The normals aren't saved with the model, they are always generated as new ones.
