Beta release 70 will contain some fixes to Particle System Entities. There are no real new features, but many of the properties of particle systems were so broken that the fixes could result in visual changes. The changes are as follows:
- the alphaSpread, radiusSpread, and colorSpread properties now work. This means that if you had them set as anything other than 0, your particle systems were rendering incorrectly, but will now appear as intended.
- the speedSpread property now works on point emitters
- the start/finish properties now work. Under certain circumstances, the colorStart, colorFinish, alphaStart, alphaFinish, radiusStart, and radiusFinish properties wouldn’t work properly or would appear different to other users. The intended behavior was that if these properties weren’t set, they would be equal to the corresponding middle value (color, alpha, particleRadius).
Basically, all properties should be used correctly now. We apologize if this affects your content in any way. Let us know if you have any questions!
