Yes, I am here . Not much has been done as I have lost the interest in it and to be honest it is not the best time to release a car because Racer is changing with every version very quickly now, but as soon as 0.9 comes out, I will release the Kappa too.
There is nothing to upload really. The car is far from done and as such I will not release it to the public. It is not working very well in recent Racer versions, the shaders have changed, the interior dials have changed their position... When 0.9 comes out, ths car will be out too. And I have a feeling it is not going to be the only car released.
