Hello,
I am trying to render a Guassian Splat in an 8th Wall world tracking AR experience. The model looks fine in the viewport, but appears overexposed when viewed in AR. I attached an image of the overexposed version, but am limited to one image so cannot provide the viewport version that looks normal for reference.
I suspected this could be due to blend settings, but I’ve tried all sorts of combinations that all seem to produce similar or worse results. Including the following which I have seen suggested elsewhere.
const material = this.entity.c.gsplat.entity.gsplat.material;
material.blend = true; // Enable blending
material.blendEquation = pc.BLENDEQUATION_ADD;
material.blendSrc = pc.BLENDMODE_ONE;
material.blendDst = pc.BLENDMODE_ONE_MINUS_SRC_ALPHA;
Attempting these values below, in a script on the Gsplat object, fixes the overexposure and the opacity, but then the splat has warped blobby geometry.
const material = this.entity.c.gsplat.entity.gsplat.material;
material.blend = true;
material.blendEquation = pc.BLENDEQUATION_ADD;
material.blendSrc = pc.BLENDMODE_ONE;
material.blendDst = pc.BLENDMODE_SRC_ALPHA_SATURATE;
My best guess is that something is different in the way the gsplat renders in AR vs 3D viewer, but I am not quite sure how to go about fixing this. Thank you in advance for any guidance.
