[A17] Plant in growhouse does not receive light from sunlamp

[Toast]

A cold snap came and I had to throw a growhouse up pretty quickly around my plants, so it ended up having a few roof support pillars in not the most elegant places. But my two sunlamps still completely cover my indoor plants with their light footprint (https://steamuserimages-a.akamaihd.net/ugc/861729956025176915/BD8AD0D40430D95A56AE5AEC53A7C99A1D51B173/). Despite this fact, there is exactly one plant that will not grow because apparently it is not getting any light from the sunlamp. In this picture you can see the one ungrown rice plant is only getting 50% light (from the torch) even though the lamp is on: https://steamuserimages-a.akamaihd.net/ugc/861729956025177166/E97E4E734B7291CDFDFD806F22EA5A0491D698DD/

The only explanation for this seems to be that the support pillar is directly between the lamp and the plant on the diagonal, so perhaps the pillar is blocking the light?... except that there are two other plants directly behind the pillar on the same diagonal, and as you can see, they grew and were harvested. They are not receiving any overlapping light from the sunlamp to the south. If it were the case that the pillar was blocking the light, I would expect that all three of those plants would be stunted, but they are not. So I am unsure what's going on here. Why does this one single plant not want to grow here?

I am using the Prepare Carefully, Mad Skills, and Trading Spot mods. But it seems unlikely any of them are related.

The rice plant receives light from the sunlamp when I removed the pillar. I tried removing the torches before removing the pillar and it had no effect.

It does seem to be somewhat finicky. I removed the other sunlamp added some walls. Those 2 selected plants still receive 100 light.

That's interesting. Still seems to be rather strange behavior. If pillars/partial walls are meant to block light, this is not the result I would expect.

It is maybe linked with this kind of strange obstruction due to walls in effect areas :

In this topic it is showed for tube televisions but it is possible it is the same for sunlamps.

The lighting system can be a bit confusing, but I think it's ok. Solid objects block light but not completely. Light can travel "around" solid objects, but doing so "costs" more. It had to be done that way, because we don't want to suddenly cut the light if there's no line of sight. In your first screenshot the rice plant is only getting 50% light because it's simply too far away from the sunlamps (because the light had to travel around the pillars). Light traveling around solid objects can seem unrealistic, but in real life everything reflects light, so it's an attempt to simulate this behavior. Thanks for reporting though.
