Looking great, so far with X8.
Here's a suggestion: Chief Architect's renderer is decent quality, but godawful slow relative to other rendering systems. That's just a fact, its the slowest renderer I've ever used.
I have for example Lument RT on my system, which is a newer real time rendering system. Lumion is another real time system that is even better quality, but more expensive. For a comparison of time difference of both of these vs. Chief, I could produce a high-end 2.5 minute animation (HD, 4500 frames) with advanced lighting, plants, animated figures, cars, birds, and special effects with Global Illumination in about the same amount time that I can produce a single high res ray traced image from Chief. I'm not talking 2x as fast, quite realistically they are 100x faster. Both of these systems import files from Chief via DAE perfectly. The textures and everything else are perfect and intact.
But there is no lighting information sent over as far as I can tell, which is a bummer. Both of these real time renderers can turn on night scenes automatically just by changing the time of day to dusk or night. The lighting information is there in the Chief models...I just wish that it exported via DAE or another format. One possible option...replace the obsolete 3DS format with FBX export, and include the lighting info in the files. Or just add it to DAE if that's possible. But opening the option to use 3rd party rendering systems is very worthwhile considering the time impact in Chief.
