Particle playground sort order9/20/2023 ![]() ![]() So I have first to reimplement some sine and cosine before making the SPS test. This is really painful because WASM doesn't provide any math function like sine, cosine that are massively used in the rotation computations. don't call setParticles() at all, don't use the billboard mode, and replace the planar particles by real 3D particles visible from everywhere (tetrahedrons or tiny low poly spheres)īTW, I'm currently working on my poor free time on a wasm test about the SPS computation process to check if this could be really improved with wasm. Alpha blended meshes, sorted by depth ( distance to camera). if the camera needs to rotate, call setParticles() only on demand : General Order Rendering Groups Alpha Index. UN-93 Luna UI now can upload builds to Luna Playground. Just do something with a handful of dirt, dear, and say any sort of legal. Sorting Fudge Use this to affect the draw order. in an asphalt playground then the white boy is kissing the black girl. don't call setParticles() at all if your camera doesn't need to rotate (but only to zoom in/out, so no need for billboard there) and keep the planar particles : Fixes unintended culling EN-730 Particle sort order zdist based on abb fix EN-746 Culling. Sort Mode The draw order of particles can be sorted by distance, youngest first, or oldest first. while in case of the screen space overlay UI was rendered after Particles, so we saw canvas in front of the Particles. But in screen space camera particles was rendered after canvas so we see prticels in front of the UI. That said, if you still want to use the SPS with billboard because of its extra features (per particle color, uvs, intersection, picking, particle depth sort for alpha blending, etc) and if you want to get higher performance, you could consider these leads, knowing that the heavy computation is done in setParticles() : Summery: As for both of the Canvas and Particles sorting layer was 'Default' and sorting Order was '0'. Since the cannons barrel radius makes a square, some particles are created at the top of the square rather than the bottom which makes it look unnatural. Im having trouble getting the particles to fall in a continuous stream. Please note that in order to use Particle Pro you need to have Stardust. ![]() That's why I often recommend to use the legacy particle system or the sprite manager when people need the billboard mode for planar particles only because they are more powerful when dealing with huge number (> 10K) of particles. Right now Im using particle playground to make particles fall out of a pipe. The easiest way to create professional particle effects in After Effects. Now anyone with access to a Lightning co. and rotations are the heaviest computations in the process. Before Summer 20, users had to obtain a courtesy license from Salesforce to access the Publisher Playground app. ![]() So when using the billboard mode, the SPS needs to rotate each particle for you under the hood so they always face the camera. Whereas the sprite manager or the legacy particle system always render their elements (sprites or 2d particles) directly in the screen space in a certain manner, the SPS, even in billboard mode, still computes everything in the world space. ![]()
