Smoke particle system.

Script based particle system for trueSpace workspace. Some sample scenes are also available on the web page.

Amazing Clinton!
Loving the possibility to be able to Attach the Particles to an object!

Is this the way that the Default setup should be working?

Yep, there is no "default" particle system because of the huge number of possibilities, so it's setup to be obvious that something is happening and that it's working.

Have been trying to Import more Flipbooks from
https://blogs.unity3d.com/2016/11/28/fr ... flipbooks/
Can not get the Alpha to work like you have accomplished with the explosion flipbook.
What is your secret getting the transparent background?

The trick is a custom alpha shader that only reads the alpha channel of the image.

I am using your Alpha shader
I supplied a different 10x10 images to it, both Alpha and or Diffuse with no luck so far.

I am using your FlipbookExplosion scene

Edit: I guess the key is using the TGA format.
I was using png

I don't understand. The link provides TGA files, so how did you end up with PNG files?

I was trying the Contact Sheet Generator with Alpha Mask script.
Using the Sequence images.
Edit: Success saving as a BMP.

Ah, so alpha doesn't work for png files, but it does work for bmp and tga. Good to know.

Are you sure that the Alpha, Fade In, and Fade Out attributes are working?
Can you upload an example showing how it works?
With your first Particle System, I can clearly see results when using the Alpha attribute instantly.
With your new version, I am not seeing any results at all.

Try the snow scene. The snow flakes fade in.
I don't know what you mean by "your first Particle System" or "new version".

Thanks, I see the Alpha attributes working with the Snow scene.
I was referring to your first version being your Experimental Particle System::
viewtopic.php?t=5903&p=57291&hilit=Particle#p57291
and your "new version" being in this thread.

I see now that in order to use your Alpha, Fade In, and Fade Out attributes you have made a modified AlphaTexture.
Seems to me that the default material for the Dot object should include this modified AlphaTexture so that the Alpha, Fade In, and Fade Out attributes works. Presently they do not work.
That said, I am not sure about the pros or cons.

I have been experimenting with your modified AlphaTexture, seeing if I could apply it to the FlipBooks "Alpha and Mask" materials, but seems to be a no go, and as you have already mentioned it also uses a different AlphaTexture. Meaning that you are not able to use the Alpha, Fade In, and Fade Out attributes with the FlipBooks.

I see.

Good call on the Dot object. Attached is the updated version. Website update to follow.

Right. The fade in/out is passed through uv coordinates and the flipbook uses uv so can't have both.

I just found this sprite sheet viewer. It just became free and might be useful for the flip book particles.
