only 4 images selected by COLMAP as view directions optimized by 3dGS

Hi everyone, I recently tried to use 3dGS reconstructing objects from 2d images rendered by blender. I have taken around 90 pictures orbitting as a sphere (maybe in a bad way for colmap). Taking certain latitude, the incremental angle varys from 22.5 to 45 degree. I guess this is even too large for colmap? Because the convert.py only select 4 images from these 90, and only such narrow view is optimized by 3dGS, which results vey poor reconstruction. log.txt As seen from the log, only 4 iamges are chosen to reconstruct. I'm wondering if there's a standard for image selection, is it essential to have very continous viewport transfer?
