Transient Shadow Analysis Objects in Proposed and Existing group would cast shadows same colour as their material colour. Transient Shadow Test image can be rendered using CPU or the GPU. Open the Application Settings > Calculation tab and choose the desired Rendering method. (GPU render require a compatible NVIDIA graphics card) Specify location by selecting the corresponding climate file location in Project Settings > General tab Open the Render dialog options > Transient Shadow tab and set the required test...

Rendered image is too bright. Most objects in the image are washed out and are not visible. Adjust the exposure using the slider in Render dialogue. This linearly changes the image brightness. if the image is too bright or too dark, the level of the brightness can be adjustedby changing the exposure level through the slider. In Path tracing mode the slider updates the image immediately without a need to render the image.   In Radiance mode, the exposure takes...

Two Monte Carlo backward ray tracer are provided: Path tracing and Radiance software. Iterations N: “The error in the Monte Carlo calculation of indirect illuminance will be inversely proportional to the square root of this number:four times more samples are required to decrease the error by half. In Radiance option: This value corresponds to ambient […]

About Material Dialogue Material Dialogue can be opened by clicking on the material dialog icon on the tool bar or by clicking the Tools Menu then Materials. Using of the Material Table requires enabling the option by ticking the Use Material Table box on the Materials Dialogue. -  Using Material Table Mode The material table is empty for a new project. The list is populated with the materials based on the layer colour RGB value when the model is converted for...

BS EN17037 Illuminance (SDA) Criteria Illuminance Criteria UK National Annex The UK Annex is intended for "hard to light" dwellings. The illuminance targets for BS EN17037 SDA can be accessed via Project Settings Climate Daylighting tab. The target Lux is to be met for 50% of the time over 50% of the space. Notes (Also Applies to EN17037 Criteria too) Daylight Hours: The hours of daylight are determined by rank-ordering (i.e. from highest to lowest) the 8760 values for diffuse...

BREEAM Daylight Factor Criteria Terms and Definitions Average Daylight Factor The average daylight factor is the average indoor illuminance (from daylight) on the working plane within a room,expressed as a percentage of the simultaneous outdoor illuminance on a horizontal plane under an unobstructed CIE Standard Overcast Sky. Point Daylight Factor A point daylight factor is the ratio between the illuminance (from daylight) at a specific point on the working plane within a room, expressed as a percentage of the illuminance...

 Open cutback dialog by entering MBSCutback command or By pressing the Cutback icon on the mbs tool bar. Select group Select Sky type. For ROL cutback Sky should be set to Uniform. Orientation is the surface orientation where the calculation point lies on.Set the Orientation to Vertical for Windows, and Horizontal for ROLAlthough ROL calculation is for a point on a horizontal surface(working plane), the rendered image for points deep in the room might come in low resolution.You may pick...

Why are Mesh colours not seen in Autocad? Mesh objects are visible by layer colour in Wireframe view. Change view to Realistic/Shaded to see the individual Mesh face colours. To see Mesh face colours in Wireframe view, explode the Mesh so that it gives faces whose colours can be seen in any view.
