Ati drivers 10.7 products weird physics

[diedir]

Hi all

 

before updating the graphic driver to 10.7 on an HD 5850 with vista 64 with LE 2.40,

i never notice that:

at beginning of my scene all is ok but near the end of the terrain limit (20 meters ~=),

while playing with my car, jumping and crashing, suddenly the physics stops to respond :

the car stays in the air with no steer and a limited to nothing torque (wheels turning a bit then stop)

 

only solution is to start the scene again...

 

i try to add a "SetForce(model)" in z axis to force physics but only work a time...

 

is it the ATI driver or otherwise an Newton physics issue ?

 

i don't try to reverse driver, tricky thing i assume...

 

am i the only one in that case ?

 

thanks for answer or testimonies

What you describe sounds like your vehicle is reaching the end of the newton world.

Normally it is 500m in each direction (from Position 0,0,0).

Try SetWorldSize(Vec3(1000)) or even a bigger value.

Thanks for your answer

never knew about that end of the Newton world (wasn't 12.21.2012 ?)

i am curious though while my world is 256x256 wide

 

but i will try if it happen again... soon i presume

 

thank you

I do usuallly SetWorldSize(Vec3(50000)); hasn't shown any negative aspects yet.

For camera range I set usually Vec2(0.001,5000), it's not too far, not too near and handles the retarted 32-bit float range nicely.

Additionally I need to set the camerarange for lights also (wtf? but this is how the engine "works"), if you want to have lights inside a light cage which "project" the cage outside.

thanks Lumooja for your tuning tricks

 

i will try that later too,

for the moment, i set the world at Vec3(1000) and cannot reproduce the weird physics since...

hope it vanished

Try setting it to something lower and check if the problem occurs again.

Then you know if it's the newton world size, or some kind of bug.

i found a big problem when my model hurts a big static model

 

when my model hurting static tubes in the AABB of the static model

 

then my car get frozen to static even adding force to move it fails

 

i put "worldsize" very big size with no luck, physics inside static physics not working for me.

 

after colliding with static meshes, the model sometimes flies far in the sky and get frozen;

the mass of the car is 2.0 to stick a bit with reality.

perhaps it is not enough ?
