Re: Shader ball Example scene

Thanks Sharly!

Oh yes, the dark ball... it is made from this material, which I had left over:

The print time for the big lamp was now a little under 2 days.

Re: Shader ball Example scene

Had less to do then I thought, so I already decided to do a yolo-print with the transparent. Looks nice. You can see the infill pattern, but that would be nearly the same with white filament. I only have to make a base extension to lower the LED all the way to the bottom, or the base will be complet...

Re: reflectivity on a black material covered with a clear one

This is very difficult to answer, as it will likely depend on the specific materials, how they are manufactured, geometries, and illumination. If the materials really have the same IOR, and they are well bonded (i.e. without air gaps or bubble inclusions), then you will get no surface reflection. So...

Re: reflectivity on a black material covered with a clear one

ok, now the situation is much clearer. Yes, a real smooth black surface will also show some reflection. There is no perfect black, and if it is smooth it will be glossy/specular. I've attached a modified scene with a camera and mesh light at a shallow angle (don't try this with Sun, an inifinite lig...

Re: reflectivity on a black material covered with a clear one

Same here, just had a look and not quite sure what the problem is. The scene looks fine to me. One interpretation of your question I could see is that you want - in total - only 0.1% refelction :?: As you have a glass surface at the front, you will always have the 4%-component from that. From both m...

Re: Shader ball Example scene

Nice progress ! btw what material are you going to use for the ball lamp to get enough light passing through the geometry ? the same ? Thanks! Yes, probably standard white PLA again. I also ordered some transparent PETG which I consider trying also, pending a test print. Based on past experience th...

Re: Shader ball Example scene

Almost done with the remoddeled large lamp, still have to add holes for wires. The inside is hollow to save material and optimise light output, see attached image. Hope it will go well, note the print time and material usage in the bottom right corner :lol: Couple more things in the pipeline to prin...

Re: Loop Textures

The following links to a short tutorial for photoshop. The principle is actually quite easy after you read and understood how to perform it. Thanks for the suggestion, it's always good to know methods to achieve certain looks. Indeed, with metal surfaces I have seen different looks, like "brushed",...

Re: Colour correcting HDRIs

I've been slacking off on this, but i've not given up ;) Anyways, a bit more pointing me in the right direction might be helpful. I've been looking at the displacement shape as you suggested but (in the LuxCore code) I don't see how that shows a node tree. There it seems to just load a texture map. ...

Re: Random optics stuff

A current WIP to redo a setup visualisation, for which I was trying to make a clean model of an optical table. The top plate with the holes will be implemented into my OptiCore plugin. The screw threads in the holes are done with band texture as bump map at the moment. The metal texture will also ne...
