Create a (static) gallery like scene

Hi,

I am an arts student and want to create a 3D visualization of a booklet. I had a long wall with the pages, nicely arranged and lighted in mind. The only interaction would be to move along the wall and jump to certain positions at the wall, e.g. to different chapters. I am using Blender and so I found your software.

Now, I created the scene, added a lot of (point) lights, enabled shadows of frames onto the back wall. I only added ~20 pages yet. In Blender (viewpoint shading) everything works fine, but when the scene is rendered by your engine, it gets very laggy. I checked the performance information in the console (https://justpaste.it/6fgkl). There are a lot of render calls already (~200).

So I started to search how to improve rendering performance, and found some resources from this forum here. But I am not a programmer, and not an expert in Blender either, and could not get my web application run faster. Removing lights and frames of course helped.

One optimization method mentioned here (https://www.soft8soft.com/docs/manual/en/introduction/Optimizing-WebGL-performance.html) is to reduce the number of materials loaded. Every page/frame has its own texture and so its own material, I guess. But I do not understand how to use one material with multiple textures. I do not understand coding.

There are several warnings that my materials have more than 8 textures (13) than allowed (for ios). I guess this is reducing performance as well. What went wrong there?

Another point mentioned in (https://www.soft8soft.com/docs/manual/en/introduction/Optimizing-WebGL-performance.html) is to reduce the number of lights. I like the effect of the many lights, the specular highlights on the floor, the shadows on the wall, etc.

Now, my scene is static besides an observer/a camera able to move around. So I think there is room for improvement. But I am a bit overwhelmed with the possibilities right now.

I hope someone could clarify how to make the scene work in the browser by not reducing the look/quality too much. If coding is needed (I did not even understand the puzzles right now) could someone please be specific on what I should do or point me to some step by step tutorials?

Thank you very much!
