Hi
I am currently trying the motion blur and a blast of reactor here is the result of my first tests. I am not at all satisfied, so if you have any advice please feel free, thank you
soon

hmm it seems that the camera is moving with the same speed and direction with the car. Then its normal that no motion blur will be applied to the car.
Is that the case?

[hod]

Yes it does, this approach still leaves a problem with the wheel visible as it should run faster and thus have the circular motion blur, well I'll deal with that later, so I preoccupation most is that I can not simulate the jet blast and the heat they emit.??

You can fake the jet blast reasonably well, try modeling the blast as a mesh, and set its material to a null-scatter mix and putting a bright light at the engine itself. Looks something like this: http://www.luxrender.net/wiki/LuxRender ... er#Example

It really should be an emitting medium, but Lux doesn't support those yet.

As for the heat shimmer....as best as I can figure out from googling, the shimmer comes from the heat changing the IOR of the air in the exhaust. Which would require heterogeneous mediums, which is also not supported yet. Not sure there is any way you could fake this one.

what you said is pretty discouraging, but only the effect my image will not that I want.

good evening
how the march that. I just créate a scene in blender then illuminated by a sun on one of my items I apply a rough Glass texture , but as I make the scene luxrender makes me a full shadow as if it were a element without transparency why? thank you in advance HoD

Hi
I board again changes, but I have difficulties to get a proper lighting as you can see. I board try setting nonbreuses never succeed to eradicate the area of overexposure to the vehicle. also how can you set the hardness and the lamps and specular materials
Thank you in advance the help you can give me
