Dear friends,
with this revision, we have basically made our big step towards final release, in fact, this release candidate could be the base for the final release. And we simply, "touched" a lot of important areas in Thea.
First of all, and most crucial, is that we have re-calibrated the display output along with changes in sun-sky system. All lights and HDRIs have been confirmed with respect to their power. We introduced also new units Watts per nanometer (W/nm) for representing power distribution and removed the - obsolete now - multiplier for point lights. These changes won't show much difference when trying to render a scene (quality-wise), but for older scenes, sun-sky has to be regenerated (disable/enable sky) to get proper render. This is why, if you are in the middle of production rendering, that you should not jump directly to this revision, as it generally needs some re-tuning on the lights.
Moving on, this revision is the most robust one, geometry-wise. Displacement, anisotropy, bump and normal mapping have been considerably improved. Anisotropy is now working excellent even on the most difficult meshes (mixed flat/smooth meshes). Normal and especially bump mapping are better than ever, without exhibiting the high frequency noise ("fireflies") that takes so long to clear in unbiased modes!
Apart from the above, there are also other small fixes along with full string table for translators (to be published). As always, you can find the new revision in the usual thread: http://www.thearender.com/forum/viewtopic.php?f=61&t=1849

SOLO, I just got Thea, and playing around with it, I'm trying something like your 2 enclosed images, but not getting shadow results, can you elaborate more or show settings, and is it possible to control size of image. Thanks much.
-
You need to apply an infinite plane but set it to only receive shadows (not to be seen). That's actually where the shadow is cast, not the background image.
Then you need to fiddle around with orbiting and zooming and all as you cannot position (or scale) the background image itself.

A quick update, Thea Render RC4 is available with enhanced IES support; now, you can drag & drop an IES file to your material editor.

Use IES on materials?

The first official release version of Thea Render is now available at the development forum.
@unknownuser said:
Dear friends,
this is it! The first official release version. It is basically like the previous revision with only a few minor fixes.
We want to thank you all that contributed with one or the other way! We will continue with the same and
faster pace from now on and we have already some very powerful features on the way!

Since I missed installing revisions 2 and 3, can I just install rev 5, and that will take care of all the other revisions,
or do I need to go back and install in order.
Thanks -
Just install over the version you have. No need for incremental installations, no need to uninstall the earlier version.
-
Thanks notareal, I was hoping for that.

Little heads up with latest Thea Render development: http://www.thearender.com/forum/viewtopic.php?f=61&t=5161
Invisible object can now cast shadows and caustics for all engines. Great if you need to see trough wall or objects, but still need to get proper shadows and caustics from them. I imagine this also could be used also with 2.5D plants and so...
Changes Log

Thea Render v1.0.7 Revision 481 (16 March 11) available at the development forum.
@unknownuser said:
Dear friends,
this is another quick revision with small fixes here and there.
Quality-wise, there is a small improvement when rendering non-power-of-2 textures (for example, 200x200 instead of 256x256); they will appear sharper. The difference will be negligible though for high-resolution textures. Additionally, an important bug on MacOSX reading XML files from SU plugin has been now resolved.
One nice addition in this revision, is that you can place (manually) the sun so that it matches the image used for sky illumination. This was asked in the past as a means to "align" the sun and IBL. This is possible because - starting from this revision - the image, in the IBL slot, is displayed in the OpenGL gizmo, whenever the sun is selected. Check the description page below, to see the series of steps needed to take advantage of this feature.

Thea Render v1.0.8 Revision 486 is available at the Thea development forums.
This revision has also 2 major improvements.
First is the improved sampling of diffuse and rough glossy surface in the presence of IBL for Adaptive BSD method. Especially, when the lighting in the IBL has a lot of variation.Second, a big workflow improvement has been added. We can now save Sky/IBL/Sun settings with a few clicks and easily apply them later in another scene. This way, you can easily now create your sky libraries (including your sun settings) and restore them with a simple drag & drop in the Viewport.
Changes Log
Thea Render v1.0.8 Revision 486 (30 March 11)
- Fix for evaluation of grayscale non-power-of-2 bitmaps (bug introduced in previous public revision RV481). (all engines)
- Hemisphere gizmo in OpenGL Viewport displaying HDRI is now independent of IBL intensity. (UI)
- Added ability to save sky settings (through browser context menu) and restore by simple drag & drop into Viewport. (UI-I/O)

- Corrected renaming and removal of IES files in browser. (UI)
- Fixed chromaticity for sky previews and hemisphere gizmo. (UI)
- Building of adaptive bitmap resolutions (for trilinear interpolation) is now taking place on demand (it is used only by Adaptive BSD). (memory management)
- Some code refactoring with respect to resources. (refactoring).
- Addition of secondary browser in studio, it can be accessed from Window > Browser #2. (UI)

Thea Render Revision 491 is available at the development forum.
Thea is now improved in terms of noise when it comes to IBL lighting with Reflection and/or Refraction maps defined. Affecting both, the unbiased core as well as Adaptive BSD.
Another important addition in this revision is network rendering for Adaptive BSD! This works for still images (like unbiased modes) in a bucket rendering fashion. -
Technology Preview of Luminance/Illuminance Analysis
We are very happy to announce that Luminance/Illuminance Analysis has
been added in Thea render. Analysis can be saved as a html report.Feature will be available with the next public revision.
-
Thea Render Revision 504 with luminance and illuminance analysis is now available at the developement forums. A minitutorial for analysis is included in the revision annousement post.
The revision contains also some Adaptive BSD enchangements and fixes; rendering animation through the network has also been implemented. -
A little heads up and technology preview of next Thea Render release:
@unknownuser said:
Dear friends,
you know we are working hard "behind the scenes" to get the most out of Thea Render. And we are taking the opportunity, this summer period, to advance Thea to the next level. During the last weeks, we have worked on the core of the application and succeeded into achieving a remarkable speed boost that makes Thea up to 2 times faster!
In more detail about our achievement:
- Render times are now decreased between 25% and 50%. This is true for all render modes although it is much more obvious for the unbiased modes TR1/TR2 - BSD shows a speed increase as well but depends more on the scene.
- Construction of the environment (during initialization) is now multi-threaded. This means faster render startup and a more fluid interactive render!
- There is a reduced memory footprint now - estimated between 10-20%, that makes it possible to render even heavier scenes.
- The improvement is even more pronounced for heavily instanced scenes (with speed ups between 2x and 5x!) - a particular example can be seen below. The scenes that use displacement on the other hand show marginal improvement since displacement-on-the-fly is a different process to optimize.
We are sure you are going to love our new version. We are continuously working on various improvements and advances, so we believe next public revision will be an important milestone for us. Stay tuned!
best wishes
