Thanks for your videos. Is there a work around with creating a walkthrough video and sending to a client. I have tried to do it… it saves as an Avi file and the quality it very very bad! I have converted the avi file to an mp4 and the quality is still bad. Do I need to upload to a different program?
Frankly, Revit is not ideal tool to create animations. Try exteneding your camera size so that the result is at least 1080x1080px. Other than that, you are relying only on Revit's viewport graphics, which is not that great. If you work with 3D visals a lot, I would recommend purchasing Twinmotion license (you can test it for free). FBX export from Revit LT works well with Twinmotion.
You can still use Twinmotion with Revit LT even though there is no direct link. Simply export the 3D model as fbx file and you can import this file to Twinmotion. You can work on this file in Twinmotion, add assets, change materials, etc. When you change the Revit model, you export fbx file again and update with the new file (re-upload) in Twimotion. All the assets and material changes in Twinmotion remain, only your model changes. It is not as seamless as with direct link from full Revit, but it works great in my opinion. I never used this workflow in production, but my testing looks promising. One more note: is you use Twinmotion commercially, you have to pat for the license. But it is priced quite reasonably in my opinion.
