Yeah, I noticed the new branch. Is it ready? It's just sitting there for 3 weeks since the last commit.
Not sure if this is a bug or even if it is already known. Invisible photons:
Edit: Easy way of replicating it: Put DMND. Use PROP to set its type to PHOT. I first found it through a different way though. I used a laser to produced cyan/orange beam which went through glass. I noticed "empty" spaces in the glass which turned out to be black photons. Why and how does it happen though?
It's not considered a big problem because they disappear on the next frame (or at least, they do for me).
I can't say exactly why it happened without seeing the save which produced them. In most photon interactions, photons with ctype=0 (no wavelengths of light present) should be killed as soon as they turn black, instead of on the following frame. There's probably some bit of code somewhere which misses that particular check.
There are black spaces where the photons enter the glass. I agree that it's not that big of an issue though, I just thought that it looked strange.
But are there plans on making PRTI non permeable to protons in future updates? I (and I'm sure others will find it helpful too) would really like it if this is done as it would useful in transporting protons around. Another issue I don't like is how sometimes when protons go through PRTI/PRTO, it changes their temperature and thus also their tmp channel. Please fix these.
Edit: Please reply to me, I really want to know if there are plans on fixing these portal-proton issues. I am working on a compact project involving protons and it can't work unless portals work properly with them. I'd like to know now so that I can look for other ideas instead of waiting for a fix for this if portals aren't going to be fixed :/ There would be no point in me continuing the project in the current direction if it isn't going to work..
