Adding wind/fan force to pyro sims May 8, 2018, 8:33 p.m.

So I'm trying to do a simple task. Create smokeless fire on sphere > Add Wind/Fan force.
Nothing seems to happen. I added the Wind force by clicking on it from the Drive Simulation tab, then clicked on my pyro sim, hit enter.
I put ridiculous #s for scale force and everything else but nothing on my pyro sim is actually moving. Anyone have ideas on why?

So here are the different formats I've tried. It seems that JPEG gave me the best result. It doesn't really give me a proper alpha to change the background color but I guess this will do for now.
I think it's a color clamping issue with all these different formats and they're all giving different results. I really wish there was an easy option to clamp the colors better with any format so it's close to what the user sees on screen. All this underlying format issues are really confusing to me.

looks like a difference of opinion on whether the image should be unpremultiplied. Don't use weird formats that some software expects a certain way. Avoid targa, png, tif, etc. Stick to exr and jpg, they are the only known quantities when it comes to image formats. Avoid photoshop if possible.

Thanks for the suggestion jsmack. I've tried to use EXR as a image format using “Save to Disk”. The image size of the EXR renders out a LOT smaller and it also cuts out all the alpha which moves the image around when viewed in After Effects. I kind of have to use Photoshop/After Effects to edit my images as well. As for JPG, it won't work since I need alpha out of these images. These turn into sprite sheets which gets used in a game engine. I'll keep trying different method though. If there's any more suggestions, please let me know.
Thanks all!
