              Hi!
I assume there’s a typo bug in AddUniform method in both CustomMaterial (source ) and PBRCustomMaterial (source ):
if (kind.indexOf("sampler") == -1) {
    this._newSamplerInstances[kind + "-" + name] = param;
}
else {
    this._newUniformInstances[kind + "-" + name] = param;
}
The condition should rather have !==  like:
if (kind.indexOf("sampler") !== -1) {
Thanks!

              I would say yes as well adding our friends @nasimiasl  and @MackeyK24  who are using the custom materials ?

              hi thanks for notice that is true but the main reason the ‘param’ parameters not used so much i guess we can remove that because we need update that parameter after effect be ready

              thanks for the response, my use case is that I use param as an “initial” value for float uniforms that don’t need to be updated
