Maybe they could just combine Chronosculpt into Layout?
When Chronosculpt first came out as a sepearate module, I thought...this will not last long, and scratched my head to why they didn´t implemented it directly in Lightwave, I could understand they would like to expand something that could attract other software users, but
for me at the time it wasn´t an option and thought it would probably have more impact to a user base already there..and to strengthen the option to have the user base intact for a lot longer.
Later I got Chronosculpt for free together with neuronmotion baked in to one of the Lightwave sales, sadly I do not use them for various reasons.
Combining Chronosculpt at that time was out of the option I think someone from newtek said, different times now..and I think it would be wise, or if metamorphic is better in most regards fill in the gap
between Chronosculpt and metamorphic, metamorpich however, doesn´t seem to work on higher res meshes which I think Chronosculpt did.
For me it is foremost important to have the option to sculpt in much higher density models, as well as creating new topology ala dynatopo...
but it also needs a way of saving and deleting various levels without freezing and delete original and reload the model.
The lack of these features kind of pushes me away from using it.
