    STARTDECL(ph_renderparticles) (Value &particlescale)
    {
        CheckPhysics();
        if (!particlesystem) return Value();

        SetPointSprite(scale * particlesystem->GetRadius() * particlescale.fval);
        particlematerial->Set();
        RenderArray(PRIM_POINT, particlesystem->GetParticleCount(), "pC", sizeof(float2), verts, NULL, sizeof(byte4), colors);
