Thanks for the explanation. I am already very happy with the material preview (see screenshot) that updates with different material settings. I am not looking for a real time preview of the render, just a render-viewer cycle from within Blender would be a great help. I tried to dive into the code of the exporter but I still have to understand how python works, especially all commands related to the operating system. My compliments for the render engine, it is really amazing how nice it looks. I like how the red of the sphere is guided through the walls of the thin walled glass cube towards the front of the cube.

I created a test scene for corona to get a feel how the materials work. The render took about 1h 11 min. The render of the complex Suzanne shape (the monkey) was noise-less relatively quick, but there is still some noise behind and under the glass cube (with thin walls). And for those of you that look at the details, I made an error in exporting the spheres: they looked perfectly round in Blender as I applied the smooth shading. However, I should have subdivided them just as I did with the monkey.

Nevertheless, I am very impressed with the quality of the render. The downside remains that sometimes the render stops without a clear indication what is wrong. The last time I had to change the global illumination setting from path tracing to HD cache to make it work again. And I would love some kind of preview. Currently I need a lot of export-render-edit cycles with constant switching between Blender and Corona.

Here is the result with the 'flipped' lights.

At the bottom of the lamp, around the lights, it looks as if the shape is lit from the inside. Is this the result of the GI algorithm? Around the light closest to the camera I tried to close the inside of the hole around the light. This didn't help. Then I put a mesh with some dark plastic material around the inside. This finally solved the problem. See the attachment where I indicated the problem area.

I checked the normals, they were pointing up. After flipping them it was alright.

Haven't found a solution yet to the install problem. Even worse, yesterday I installed a 64bit OS on my main computer to be able to run Corona there. I had a portable installation on my laptop which I copied one on one to my desktop computer... it didn't work. Only after installing Python separately I was able to get it working again. I even have a material preview in Blender, but no render preview.

Dear all,

I created a lamp in Blender based on the shape of the logo of air traffic control the Netherlands. As you can see in the attached image I have a problem with creating lights inside the spots. I used a flat circular mesh with a light material. It seems as if it emits light in the wrong direction. I still have to try to flip the emitting plane, but I was also looking for an option to make the emitter two-sided. Is this an option? Or is there a special setting to make the direct light of the emitter visible to the camera?

I obviously also did something wrong with the render-stamp. Or is this a bug in the Blender exporter? I had to tweak the Blender exporter to make the exporter work, so may be I broke something. I removed all references to the corona_path with a static definition of the path to the Corona executable. Unfortunately I still am not able to see the rendered image from within Blender. So I manually start the render with Corona standalone with the exported files. If someone has an idea what I did wrong or has similar issues I would like to hear it.
