Rackscha@ thank you, but I didn't write anything about your shader. BTW it looks totally awesome man!

Hi,

@3run Sorry, I didn't ignore your message but I'm still busy on the Vehicle integration . Vehicle is quite different from prior versions so I still need to integrate some new APIs while keeping it easy for GS users.

I'll dig a little deeper on the destruction, after solving the problem on Vehicle integration (Soon).

Best regards.

@3Run: no this reffered to your problem with kartoffels paradox demo

Rackscha@ I got it now Thank you for information
3dgs_snake@ Great to hear mate! I can't wait for it!

Yesterday i added a portalrenderer ontop of my cutoutshader.

The blue point on the portal is for debugging and marks the closest point on the portal to the camera.

Why do i need the closest distance?
We all know, if a portalcam moves backwards(as we do), it might pass a wall behind it and the obstacle is rendered. But we dont want it. SO i adjust the clip_near value of the portalcam at runtime to allow a freelook at my target.

see? The block is placed directly behind my portalcam, but the block is cutout by the clip_near value when moving backwards.

Sadly, it still has a flaw when the distance is too big and we rotate the cam. To much will be clipped away, because of the frustrums pyramidshape

Need to fix it somwhow

edit, the problem:
from far away

a slight turn to the left

Havent fixed the viewclippingproblem yet, but tried object transition.
Using an action which creates a clone from its parent and moves relative to the portal, it went fine.

kollsition decision between portal and wall is a different thing :|

nice!

but it seems like the portal-view's position / angle / arc / resolution is slightly wrong

No the resolution is equal to the screen.
The portal is a bit smaller then the tunnel its placed in, thats why it doesnt closeup with the wall/corner

edit: double post cause of internet connection...

I runned demo with portal on my new PC (on which I've finished alot of games, such as battlefield 3 on high settings) and I got about 30 fps and jerking movement, but portal itself is awesome. Long time ago, I had an idea of how to do the same, but without shaders, maybe I'll give it a try. Anyway, is that portal shader so 'havy'?
