Greetings! So, i’ve been messing around with the raycasting extension and started making a project in it, and it was going great until my problem occured. Problem, Okay so the problem that happened was that when I placed a door that the player was meant to walk through it was invisible when testing! it still was intractable but just not visible unless collision was enabled on it. This is annoying for me because It makes me have to make workarounds for things and this can become annoying quickly. I know this is a recent thing because previously this behaviour did not occur at all. Does anyone know any way to fix this? Thanks! ru040076 ---

I had a similar issue with a game I’ve made, the only option is to go to an older version of the raycast extension as of right now. ---

There is probably a better way of doing this but I prefer going into someone elses older project and making a copy of it, deleting all the code but just keeping the older raycasting version. ---

The project seems almost glitched.. for some reason the tile map renders incorrectly and gets screwed up, could be the raycasting version
