( post, there may be other solutions now)Ĥ. Some times solutions are simple (like making sure you’re rendering from a perspective view or camera view)…or merging the problem scene into a new clean scene.

My render has black splotches/artifacts:Īnswer: There are several variations on this problem.

Quick answer: Some believe it to be related to a conflict in normals, architectural materials, or possibly the use of RPC’s.ģ. My render has colored splotches/artifacts: ( post, not much of an issue in newer versions of 3ds max)Ģ. If the targeting option isn’t configured to focus all those photons on your scene then a lot if not most of the photons won’t hit anything and create the no photons stored error. So for daylight renders more than likely the mrSun is the brightest light source in your scene and would emit the most photons.

Keep in mind that currently the number of photons generated is weighted by the strength of your light sources. Quick answer: This error is mainly created whenever photons do not hit an object or materials are not configured to handle photons.Ĥ/3/09: In newer versions of 3ds Max it’s common to get this “no photons stored” error code if you’re using the mrSun with photons but without properly configuring the “Use Photon Target” option on the mrSun. I’m getting an error message “no photons stored after emitting 10000 photons”:
