For the moment I just have very few prototypes of SpaceCat. I’m not producing yet, so there are some costs ahead. It’s very encouraging to hear that Epic contacted you for a more comprehensive plugin than what 3D Connexion provides. 3D Connexion can’t provide plugins with the relevant functionality for all 3D software themselves, so what you do is really a step forwards. For SpaceCat your plugin would need two HID interfaces, one for velocity control (i.e. velocity proportional to handle deflection like Space Mouse) and one for position control (position to position transfer function like the conventional computer mouse). We would need to look a bit closer into how to implement that, but it shouldn’t be a big issue.
I suppose it would be necessary that Epic is active to some extent in my case as well. Do you know who at Epic would be the right person to look into this? I thought SpaceCat could be particularly interesting for Quixel (for positioning their assets with SpaceCat in position control) so I contacted them but I didn’t get any response yet.
What do you think my potential market with UE would be? May I ask how many plugins you sell? (maybe that information is not for the forum, so feel free to write to sundin@gmx.eu)
