So I was just test rendering with exit portals fine at work on unlicensed for sketchup
Everything looked good

Now I come home and open saved file I was just working on and camera won't work, only reinhard..
when trying to use render in camera setting nothing shows up but the exit portals...


Is some setting changed within my RT license? What should I be looking for.
both settings worked before, now only reinhard

When something works in Reinhard tone mapping mode, and not in others, it usually means that your light power balance is off, and that you should: a) Increase the light power; b) Switch to camera mode, and adjust film ISO, or/and EV value. You could also pay attention to the camera's exposure time (measure is (1/s), so go for value 1 or 2, greater values of 1600, or 800 will make your image look darker because your film get's exposed for a shorter amount of time). Your light portal is only visible because it is probably the brightest source of light in your scene. If that's not the case, you should check the normals of your exit portal plane. That's my guess, hope it helps.
