Red glow engines

[Schmelge]

Hi everyone!

 

So.. I installed ksp 1.3.1 like 4 days prior to release of 1.4

 

I built myself a jetairplane and fired up the engines. When doing that I got a red glow on the engine. It looked really hot.

 

Pretty cool thing and it changed the amount of redness deoending on throttle and hight.

 

However. Since 1.4 I don't get this red glow anymore? Did something happen to that? Could it have been a mod?

 

When I first installed I used HotTips ckan compilation wich I didn't this time. I have alot of the mods from that list except visual enhanchments. Only one I installed was Ven's when it comes to visual mods.

 

Thanks for answers

*Update 

I do get the reg glow on the ram jet engines.. maybe its just the smallest jet engine that doesnt give this glow?

Some engines have afterburners, some do not.  Each engine is modeled differently, so without screen shots, it's difficult to tell if you are seeing a bug or what.
