recently find k-3d software,open source,too.
maybe you use this .
but compare with blender is below:
do model speed which is faster?

render which is well?(when I using blender pc sometimes get hot and noise,which maybe you get this problem,too)

which is easier learning and understand ?

plugins which is easier to be find.
k-3d has many plugins but can not be find free plugins.

it looks like a hacked version of the original sketchup

i just watched a few videos on it and it seems to lack real world usage features

i think ill stick with blender

Bonjour, atpo.  K-3D is not near the good of Blender.  It is only 32 bit on windows, 64 on linux.  Blender is 64 on both.  The Mac version k-3d is not stable, they say so on download.  It has few modelling tools, compared to Blender with many.  You need so many plugins to be near as good as Blender, and almost all you must pay.  Blender has much better render engine, and plugins to many more.  K-3d only plugin with Aqsis, Renderman, Air, and 3Dlight.  Old, difficult render engines.

Blender has all features of professional expensive software.  K-3D non of these, and not used by any professional for any reasons.

All Blender is updated often, and growing large.  K-3D last update back in 2013 and no sign of any new.  Plugin builds are few between few, and not updated often new:

Blender has many all the time new.

thanks webfriends,

but in my opion blender is very tricky .sometimes can not find interface window which is using tool.

and render jpg is black background.

and pc always gets noise just like a tank engine being running.

and blender more better  than K-3d in fact.

Hello, everyone!

Atpo, the one thing you must understand about Blender is that in order to learn it, and use it to the fullest, you need to learn and memorize the hotkeys.  Unlike most other 3D applications I've tried, Blender's entire system is based on the hotkeys.  While every application has their own set of customizable hotkeys, Blender depends on them even more than the UI to engage most of the tools, and to do certain basic things.

Even in some very expensive applications, that most people go to school to learn (like Maya or 3dsmax), there are buttons for everything, and it's a very graphical interface.  Blender is different in that many of its tools are hidden, and need to be called upon with the various hotkeys by default.  This is the beauty and the curse of Blender for many people.  While I believe this is a system that encourages a much faster way to work, it takes a little longer for most people to discover, and can often lead to frustration if you never used Blender before.  Once you learn and use the hotkeys, the application opens up for you in a whole new way, and all the powerful tools and common things you may be used to doing become obvious, in a far FASTER and BETTER way than any other application.

Stick with it.  Learn the hotkeys of the latest builds (they might be different than older builds) by reading the docs and forums, and asking questions.  Blender is the greatest 3D application out there by far, and it's FREE!  :thumbupboth:
