Hi i have some problem issue with bloomeffect on this car configurator. If I drop all values to zero the problems still remain. how can i fix it? thx

Hi @petto_visual and welcome,

That’s quite strange, not sure what’s going on. Are you having a single camera with the post effect attached?

Yes, only one camera

Can you share a sample project url that reproduces this issue? I grabbed the bloom script from here, and tested on a new project. It worked as expected:

github.com

playcanvas/engine/blob/master/scripts/posteffects/posteffect-bloom.js

// --------------- POST EFFECT DEFINITION --------------- //
var SAMPLE_COUNT = 15;

function computeGaussian(n, theta) {
    return ((1.0 / Math.sqrt(2 * Math.PI * theta)) * Math.exp(-(n * n) / (2 * theta * theta)));
}

function calculateBlurValues(sampleWeights, sampleOffsets, dx, dy, blurAmount) {
    // Look up how many samples our gaussian blur effect supports.

    // Create temporary arrays for computing our filter settings.
    // The first sample always has a zero offset.
    sampleWeights[0] = computeGaussian(0, blurAmount);
    sampleOffsets[0] = 0;
    sampleOffsets[1] = 0;

    // Maintain a sum of all the weighting values.
    var totalWeights = sampleWeights[0];

    // Add pairs of additional sample taps, positioned
