I am nothing to do with TrueVision. I do not sell the engine, I just wrote a module to interface between BlitzMax and TV3D. Both modules ( lite has no source, pro has source and support from me ) require the engine from the TrueVision guys.
Can you get it free? Yes and no. You can get a version for for free, but that version is incompatible with BlitzMax. You will be able to get a new version, compatible with BlitzMax, when it's released to the public. You can currently get that version for free, but only if you bought the previous version.
And no, I don't know when they will publicly release the version which can be made to work with BMax. The official line is very soon, but that's been the official line for a year, so they're very much from the "it'll be done when it's done" school of programming.
