Bright sun glare off bodywork possible?

Can you achieve these kind of bright, star-like sun glare reflections from the cars' bodywork with post processing, like in this screen shot?



I've tried playing with glare settings in the PP file, but they only seem to affect the headlights and brake lights.

 

The star glare there would be a lens flare so it would also need something in the pp effects I think. Im sure Ive seen this at some point ingame and it can be interesting for videos and replays trying to simulate a camera. But I personally when racing dont like to see too many effects you wouldnt see with your eyes and only through a camera.

Driving with a dirty helmet visor you see some odd glare and relections too I guess but its something you really dont notice after a while. Take at look at the PP profiles and see if you can make some star lens flares from it. Possibly the movie or photo profiles could do this already.

 

It's possible...


That's probably with one of the default PP filters and weathers...

 

You do see these bright reflections with the naked eye too. I was looking at traffic while driving in the sun, and the real world view has lots more bright highlights in bright sunshine. It made me realise that AC looks quite "flat" on a sunny day, from that perspective. One of the ancient TOCA V8 Supercars games had the effect I'm after, with bright sun highlights, and it looked quite good.

I haven't played with lens flare though, only glare - that might be worth a try.

I tried all the current default PP filters, but none give that effect. That looks like a star effect in the glare settings though. It was probably a custom PP filter for screen shots. It looks pretty good on the bodywork, but then looks way overdone on the brake lights.

 

Try different hour of day in the game, like 10am. Then put reflections at a higher setting.

 

Reflection settings have no effect on the specular output of the material...they only change the resolution of the cube-map and the frequency at which it's updated.

 

Yeah, maybe it's a limitation of the material - not enough specular reflection, not bright, tight and intense enough.

 

Depends on car, and time of day. Certainly possible, and one of the coolest effects. Don't get people who want to turn it off with some custom PP

 

its definitely possible, but the downside is you have to suffer star shapes appearing on shift lights, brake lights all of the time. ideally there would be a separate glare section of the fitler applied to the body and to these "light sources" so we could have star shapes exclusively on the bodywork. for me they look so terrible on the brake lights and shift LEDs that i have the star effect more or less off.
to restore it to my filter i changed these lines (obviously could be fined tuned to look better)
SHAPE
STAR_SOFTNESS
SHAPE_STAR_LUMINANCE
SHAPE_STAR_LENGTH

e.g.:

looks ok

but now you have to suffer this (probably even more extreme when you dial in the star settings to get it looking good on the bodywork):



my preference:


lack of saturation (particularly in brake lights) due to this bug: https://www.assettocorsa.net/forum/i...on-in-pp-masively-affects-brake-lights.31314/

 

Your car looks good ears. Like you, I don't like the stars on the lights. I'll try your PP filter.

 

if you dont like the stars just set the glare quality slider to normal, i do it that way and have no stars

 

That's actually an official screenshot from Dream Pack 1 release... so very old, not the same PP anymore. However I feel like AC has some problem with these.. because like mentioned, if you get the star glares look great on cars, they get too strong on things like rev lights of Ferrari Italia steering wheel. Wish Kunos did some tweaking there, to put more emphasis on car exterior star glares, less on interior cockpit glares.

 

Based on ears' file above, I was able to produce this, which looks pretty good I reckon.



When racing you get more quick little blinding flashes, reflections of the sun, more like real life. It varies from car to car, depending on the paint finish and material.

This is my glare section. I got bright bloom with no stars by setting SHAPE_STAR_LUMINANCE=0.

@WallyM the downside is that now brakelights look a bit too much. guessing it wouldnt be very easy for kunos to separate these things out

 

Yeah. I'm going to give it a go though, and see how it looks. It would be good if the bloom could be differentiated by colour - more bloom for white, less for red, although I suppose Yebis would have to support that.

 

Hi, too much sky bloom. How to remove sky bloom and keep bright flares?
