SideFX so far has chosen to not buy or be bought by any company, but rather just invest into the tech themselves. This brought them into the position they are currently in. This position led why so many of us are here in the forum. So I guess we all kind of agree with a lot of their choices.
The immediate need for cutting edge render tech/times is currently not provided by SideFX themselves, but we have couple of the best Renderer integrations out there. And Houdini Indie + any Renderer costs less than the C4D + RS bundle.
So you can chose whatever Renderer you want with great integration (due to the great HDK) and have one built in production proven renderer together with one USD based renderer that aims to compete with the big boys that is currently in beta. I think we are in a good spot.
Do you not believe in SideFX being able to provide a competetive alternative, or is it the *current* lack of a fast, feature rich, stable renderer that you are worried about? Or is it the fact that you have to import your scene into Solaris to use it?
Personally I'm not worried about either of the options. Sure the current situation is awkward, but why not use a 3rd party renderer in the meantime? Give SideFX some time.
