      You might want to check on LightUp. It's an extension that is able to bake a lot of effects in the model and I believe you can bake only shadows too.

      I'm not sure if you'll be able to export it though, it's been a while since I've used LU.

        Easiest and most affordable way would be Blender and the Bake Tool+ Addon for about $30 I think?

        It will consolidate the maps into one map, which you can define the resolution of, and then export it to .DAE

        Or another hack is to use Thomthom Blackout plugin and grab a top perspective of the elements in black and export the viewport grab and blur it.

        Then multiply it on the texture to get the baked feel. Needs some fiddling though.

        LightUp can do a global bake but you need to be mindful of the size of your largest texture as it can crash it you let LightUp dynamically create the lighting info. There's some setting that lets you limit the final resolution of the bake

          So the 2 choices are:

          1. LightUp
          2. Blender + bake tool add on

            Those are my 2 suggestions. Might be other choices out there.

                Not from LightUp. .DAE and .FBX only.

                From Blender you've the full range of 3D formats.

                      How hard is Blender to learn? Is there a way to test this method without committing a credit card number?

                      What do you think about reimporting LightUp dae into sketchup and export to .obj from SU?

                        Blender UI is a beast to figure out. Steep learning curve. No way to trial the Bake Tool+.

                        It's be quicker to use MeshLab to convert it from DAE to OBJ

                            Sort of Animation.
                            Acute3D viewer is only flying around photogrammetry model. The only and critical advantage of it is LOD. It has 1 Gb model with details unseen in SU, flying like it is 1k SU model. Amazing. Because Photogrammetry model already has shadows baked in, even medium built PC can process it with no problem. Animating shadows is not an issue, because the environment model already has shadows fixed and cant adjust at all. The only choice is to match the existing environment shadows. Well that is good enough. However, imported geometry looks like crap because it is not shaded.

                            If I can fix that, my clients will piss their pants from excitement.

                            So Here is what I got for now - 1.Get the LighUP to export DAE, 2. Use MeshLab (or SU) to make a .OBJ
                            Right?

                                  It could but you'll need to lower poly mesh to bake the high poly info to.

                                  Knald would also bake the AO channel. Haven't seen your mesh so I don't know if it would fail or not.

                                      The LightUp demo didnt work. I couldn't get it to export baked shadows. Anyone with LightUp can you post a small DAE with baked shadow? Im desperate.

                                        Looked at Blender: Gotten really sceared by complexity.

                                        Tried LightUp:couldnt get it to export anything meaningful. Posted on forums for support, no luck.

                                        Came across SimLab Composer: it was the answer to my prayers. It did everything I wanted and more. They are really friendly with import\exports. The bake looks good. Wooho.

                                            No... Not with current available version...
                                            However, I'm sure it will be available in a future version... πŸ˜„
