Do you have "Dynamic Lighting" and "Specular Highlights" ticked in your GPL graphic options ?


I tried turning them off and could not notice a major difference although my eyesight is not the best.

I was wondering if they actually do anything now that GPUs have moved on so much in 20 years.


I have GTX1050ti


Thanks
Paul

Paul, I do keep "Dynamic Lighting" and "Specular Highlights" ticked.  Without them the car bodies have a solid color (as seen in their bmp textures in Photoshop).  With those functions enabled you see what appears as sun lightening and flickering as the ambient light at a track changes.  This is readily apparent at our developmental track in Italy by viewing with TV2 down the long straight to the unique radius last turn.

it give problem to people who do skins ,sometime all skins  main skin and engine cover  skin dont react the same way to the lighting

Indeed KARTM, that's an issue with the normals in the car.3DO that are not right.
They need to be fix sometimes and it's not a quick job...

Thanks for the replies.

Now you mention it I can see the lighting effect on cars.

It may also turn on or off, the vertex shading included on ground and wall surfaces in some tracks, like Nurburgring,  IOM MC and several others.

Although I have never tested this, as I always have had that option ticked.

Paul  GTX 1060 Ti here. I keep them ticked and there is still a huge difference in dynamic lightning GPL possibilities.But most of the time we don't see them so much .Yesterday at the Norisring, I put the Alfa Romeo 33 on the roof; And I don't remember having experienced so much difference in a dashboard color and reflection. First time I saw it, I though it was a bug.

Dashboard is very dark in normal driving, but chassis upside down with the reverberation on the clear asphalt of this track, it changed to a light grey !

I think this might illustrate.

I have been playing with extending the front wheel arch on a car.  Problem is there is a small vertical deflector at the front of the existing arch, which now is in the middle of the enlarged wheel arch.  Tried to blend it in to hide it.  Looks ok on the right hand side (if you look closely it is still there) but the lighting still shows it up on the left hand side.

Is the grid something you lay over your skins while you're checking the distortion? I never thought of that, it's clever.

[ginetto]

Webfoot; you can move the polygons of the deflector or delete them.

JonnyA; yes, when working with textures on cars is a good idea to use an overimposed grid and sometimes also a color gradient.

[webfoot]

JonnyA,

As Ginetto says, the grid is useful. I add a layer to my gimp/Photoshop file so it is easy to turn on when required. It helps with tweaking things like the shape of curved stripe paintjobs (as above), as the mip gets distorted when wrapped onto the 3d model.

[KARTM]

to remove these flap is an easy task with the Noonan  3DOED

Ginetto, KARTM, thanks for the feedback/advice. I will have a look.

Stay safe.
