Render Smoke Problem

Hi.

I want to learn physics but i have a problem. I dont know may be it is not bug but i think it is.

I create everything and click to render button or F12. Everything is fine but if i change Render->Display->New Windows, every smoke is gone. Same problem with World Horizon Color. If i change before creating smoke no have problem but if i change these things after creating smoke, render image does not show smoke simulation.

Thanks for answer.

Note: If this problem is exist is forum i am so sory but my english is not good. If you have an answer just a link or adress okey for me. I can read so lot but i can’t good explain myself.

I’m pretty sure you did miss the fact that you should bake your scene before rendering. Take a look at this tutorial and I bet you will get nice results: smoke simulation

And if you speak german this might be also interesting: Rauch in Blender 2.5

Thank you so much for answer. But i have picture with simulation, its fine. I change just Render->Display, no more.

And thank you for tutorial. I’ll watch tutorial
